Very poor customer service, the waiter was very rude when he took our order. Food was good otherwise. I wont come back again here.

Food was outstanding. The waiter provided an awkward & rude experience. Be kinder dude...you only had 3 tables.

In town for the schools family weekend. We waited a little for our table as we had 7 people in our party and didnt call for a reservation on a Friday night. Not too bad on the wait.Food: very decent food. We ordered yellow curry with pork, red curry with beef, and pineapple fried rice with shrimp, and Thai ice tea. The beef is a bit over cooked but the rest of the food was delicious. The fried rice is my favorite. It has curry mixed in with the fried rice and gave a good flavor. The spicy level of the curry was just perfect for me. We ordered an extra serving of rice to go with the curry.We left the restaurant satisfied with full stomached, and there was a line waiting for tables.

Excellent vegan food selection. Serving is good for 2 people. They have variery of non vegan food. Delicious and authentic

Consistent with other review the wait time is long. I ordered steamed chicken dumplings and Chicken Satay. Both were good. The satay portion was 4 very large skewers. It was a little on the dry side but good. The dumplings were okay, not overly flavorful and the dough was not too thick. I like a thinner dough but it was still okay. I could hear other customers complimenting their food so perhaps if I had been more hungry and tried an entree my experience would have been different. The menu has a good assist of vegetarian food options.

The man that works the front counter is very rude! Every time I go in there to pick up an order he gives me an attitude or barely acknowledges my existence. Very bad customer service!

We ordered a take out last night and the food was delicious. Authentic Thai food just like what we used to have in Thailand. Definitely one of my favorite place for ethnics food. I would love to give them 10 stars if I could. I highly recommend this restaurant.

Very clean restaurant, and very friendly staff, there is a very pleasant atmosphere here, I can not wait to make another drive back and visit again. The food was very delicious and the food it a great example of Authentic Thai cooking being that they show sweet, sour, salty, creamy, spicy and bitter this creates a very round dish which compliments the entire meal and is very delicious. Everything is very reasonably priced and very delicious, I would definitely recommend a Thai tea to anyone ordering. You guys are Awesome! Keep up the hard work, and thank you for making such an amazing meal.

Absolutely delicious. Saved my marriage. The worker is a wizard.

Ordered through Uber Eats since there was no in-restaurant dining due to covid. The steamed buns were delicious and the main course (Pad See Ew) was an extremely generous portion. I only ordered it a level 1 spice, which it was, but wasnt quite as flavorful as Ive had the dish at other places. That probably means its healthier though with less sauce/fillers! Overall, an excellent meal and Ill be ordering again!

Great food, quick service, handled a very minor error quickly and efficiently (we all make mistakes) and made good on that on the next order as promised. Right on with the light on

I just came here for a simple dinner and they really surprised me. Food definitely surpassed my expectation. I had the pad see ew and it was awesome. I would also recommend the shrimp spring roll.

Super speedy and courteous service... server made sure to pay attention to all details and loved the hospitality... good food options and great taste. Nice decor and ambience to the place.

The food is delicious! The serving is also great! The spicy level are well explained.

I think this might be one of my favorite restaurants in new haven. The food is always so good. Even delivery it came fast and was still hot.

The owner is friendly and they make great smoothies/bubble tea drinks, and their fried rice dishes and stuff with peanut sauce is tasty too!

Its edible, but no where near the experience Ive had at September in Bangkok. The bubble tea is the ONLY reason Im giving it 2 stars. I think whoever is answering the google reviews is extremely unprofessional...

Decent food! Sweet staff

Has many vegan options! Theyre also labeled as such on the menu!

Quite understaffed, went past a couple of times after dinner and saw the tables all or mostly dirty. The food itself was edible albeit lacking a certain oomph. We ordered takeaways from there twice and both times couldnt finish the dishes.

Very good Thai food, surprisingly cheap, extremelly nice stuff, pleasant decor.

If you want to get your food after an hour wait, get the wrong dish, enjoy wet fried rice, be charged for your original and more expensive order, and finally be told that the pork looks like the chicken with no hint of an apology after you ask for the bill to be corrected, then this is the place for you! (Does this look like pork?)

Ordered from here through Uber and they just literally canceled my order for no reason. Wow thanks! Guess I’m not having lunch today.

They have very good Thai food in New haven!!! Their papaya salad and Pad Thai is the best. The price is very reasonable. Love their lunch specials!!!

Had tom yum noodle soup with shrimp, amazing flavor. Also 3 flavor curry with chicken, fresh nice flavors. Should have asked to make it spicy. Excellent

The food is decent, but nothing to write home about. I have certainly had much better Thai food, but Koon Thai is reasonably good for the price and I really appreciate that you can adjust the spice level.The reason I wont order from here again is the delivery time. Ive ordered 2x from Koon Thai in the last month and both times the order has arrived in 1.5 hours+ (which was 45-60 minutes past the given delivery window). Really frustrating and disappointing.

Good taste n price

Khao soi here is standout - the standard fare is quite good too, particularly the pad see ew

Delicious! Try the steamed buns

Really good Thai food, definitely worth the visit, you guys are awesome!

Awesome food!!! Fresh ingredients.

Food is ok for the price but customer service is far from ok.

Chicken saray was light and spicy, not salty which I appreciate, delicious. Peanut and cucumber sauces for dipping are so good. Masaman curry outstanding, coconut sauce is exquisite, shrimp and vegetables were fresh. Love that nothing was salty or heavy. Highly recommended.

Some of the best Thai food I’ve ever eaten, generous portion sizes and at a great price!!

Thai food is really delicious but the food from this place is terrible. It was My first order from this place and it was just a waste .

DO NOT EAT AT THIS PLACE !!! I went in for Thai ice tea on a hot day. There was no one in sight. I rang the bell and lady came out from the back. She did not smile, she did not greet me, she just looked at me. I made an order for two Thai ice teas and she stood there and demanded I pay before she we and got them. I asked her if she could go get the teas first and she refused, waved her arms at me and told me to get out. There was also a guy who worked there defending her unpleasantness. Now, I don’t know if race had anything to do with her behavior but I am black. Anyways, they don’t deserve anyone’s hard earned money. Just my opinion.

I eat in this great spot quite often! This is my favorite restaurant to have a bite. I visit this spot regularly. The meals are very tasty, the staff is polite and the rates are fair. I like being in this spot for a rich meal.

This my second favorite thai place next to Thai Spice in Orange! I only get them thru Uber Eats so I cant review based on service due to the current pandemic situation. I like their pad se ew, and their fried tofu is TO DIE FOR.Update: Visited there for the first time and probably will just stick to uber eats. The guy was unfriendly and did not understand my question and was abrupt and rude to this one customer that was waiting before me. The woman who gave me my food was really sweet, though.

Very small welcoming atmosphere, the BEST Thai food I’ve ever had. I never leave reviews for anything but since coming here a month ago I’ve been back at least five times because I can’t get enough. The food is fresh and flavorful just delicious. The owners are incredibly sweet as well. Try it out you won’t be disappointed!

I give it 10 stars. We were a large party who arrived bit by bit at a busy time. There was only one server, who did a most outstanding job. Food took a while to arrive.....but when it did it was excellent......dunno if I wanna recommend it or keep it for me and my friends

The only time I eat Thai is when I am in New Haven with my family, And Koon Thai is our place of choice. As others have said, it is a small place with a warm friendly staff and wonderful food. The food is always fresh, well seasoned, tasty and cooked to perfection. It is a nice family owned and operated business, which I am glad to support.

Food is amazing and so is the staff! Have been twice and loved everything I’ve tried (Garlic fried rice, spring rolls, moon dumplings, chicken dumplings, spicy Thai noodles, drunken noodles and tea) Wish I lived in New Haven, would be there once a week! Stopped in for the 2nd time yesterday and was remembered by extremely friendly staff. Must try if you are in the area looking for great food!

I used to be a regular here and the only reason Im not anymore is because Im just so busy and out of the area. Any time I dine and want Thai though I aim for this place and recommend it to all of my friends, no exceptions. The owner is a great person, the atmosphere feels nice, and the food is really good. Im a sucker for curry and most of the menu is very accommodating to your needs. Very happy with this place. ^.^

Delightful place to eat. Staff were fabulous and friendly. Food was amazing and authentic. All the choices and options for food. Go here. You won’t regret it.Plus cute takeout containers.

Delicious spring rolls and Thai curries!

I honestly enjoy the dishes and service, great area next to my apartment. The cashiers are always super friendly. Would recommend to others.

This restaurant is excellent. Everything is customizable and clearly marked for dietary concerns, the food is great, and the people are amazing and friendly, and remember and greet you between visits. Come here frequently but maybe not frequently enough. Try the Thai twist drink!

I wanted to try every Thai restaurants take on Pad Kee Mao/Drunken noodles, so it was time to try this one. It was fine and would go well with beer.

I ordered catering for a business lunch and the food was delicious and arrived right on time. Was so happy with the overall experience, will definitely be going to the restaurant.

Great family run Thai restaurant! Great food, a favorite of my coworkers and myself. I was greeted and recognised after my second visit. They do a wonderful job.

Best thai food in town by far. Their stir fry is bomb (spicy eggplant is a fave), and the steamed buns are baller. Ive eaten at every other thai place in new haven and since coming here, I wont eat anywhere else, though I am a vegan, so cant speak for the meat options. It is a little oily for my liking but I havent found anything better in town yet!

I thought this place was really quite good. Excellent steamed dumplings. The chicken pad Thai was also excellent. I asked for a spicy level of 5 which is called Thai. Its their highest level of spice. And it was indeed incredibly spicey. So spicy where it was almost unenjoyable. But I was able to get it down with about three carafes of water...lol!🌶️🔥🌶️🔥🌶️🔥🌶️🔥🌶️🔥

Food was delicious but experience was a bit strange. When we got there on on Sunday evening they were washing the floors- we thought they were closed. BYOB (liquor store with great selection next door).

The white guy who works there always rude and discussing tone have some manners

Pretty good food on college-student budget. I like that the restaurant is not very busy. Attentive staff. I recommend pad thai. Curry with tofu can be hit or miss.

Reasonably authentic Thai cuisine for New Haven. Good prices. Be careful to order your food at an appropriate heat level. Their units are on the Thai rather than American scale.

The food here was amazing! The cheese-filled wontons were divine with such a creamy, slightly sweet filling. The rest of food I had there was solid, with plenty of vegetarian/vegan options along with exquisite fried rice. You can even get bubble tea here, which is more than I can say for any other Thai establishment Ive been to.

Delicious food, great service, and a friendly welcoming atmosphere...not to mention cool music. Was walking on air after that meal and I wish I lived in New Haven so i could visit it more often!! 10/10 recommend.

The owner/waitress is extremely friendly and accommodating. Great atmosphere, and location. Everything Ive had from there is amazing and I have recommended it to many friends. Pleasure to be there.

I have always been happy with the food and quality. Clean restaurant as well.

Many vegan options. Pad see ew without egg tasted amazing!

Excellent Thai food. Reason enough to have made my lunch stop in New Haven.

Wonderful owners. Delicious food. Would definitely go back again!

We visited this restaurant on a business trip. The food was amazing and the service was impeccable. I would definitely recommend it to anyone visiting New Haven.

Restaurant was very clean, food was excellent and menu had a large variety of traditional Thai dishes, service was very good and owner was very friendly. We felt very welcoming. Will be coming back again soon!

Fav spot in town. The owner and manager are super friendly. The lunch menu is ideal. They have gluten free options.

Outstanding price point, delicious flavors, well prepared, not fancy but very clean. The host was lovely--very kind and patient. Highly recommend for causual dining.

Excellent Pad Thai, and great options for vegans. Spicey Eggplant should have more eggplant than broccoli/carrots/etc., but it was very light on eggplant (lose a star).

Store is very clean, friendly staffs, speedy service. beef fried rice awesome, shrimp dumpling very delicious, and awesome noodle was awesome itself. kinda salty, if really pick one spot, otherwise very nice and reasonable costs. I love to stop by next time, too

Tiny simple space. Actually expected it to be a bit more flavorful due to good reviews. Probably wouldnt go again.

Went there last night! Our waitress was super friendly and our food was delicious! Highly recommend.

Great experience! I will be visiting next time i find myself in New Haven:) Love this restaurant!!The steamed buns were wonderful!

Good food prices and lovely owner. Been eating here since it opened! Still delicious!

Verry good food and nice place

I usually eat at another Thai restaurant but I decided to try a different restaurant with my wife & friends and I enjoyed every moment of it. The food was great, the hospitality was awesome and the music and energy was supeb.I WILL BECOME A REGULAR!!!👍👌👍👌👍...

So I have no complants about dealing with these folks. Though I havent exspieranced the food, they have been pretty normal to me this far, which is very appreshated. So I dont think what I have to ask next should reflect the rating.... I was hoping I could honestly request for you to change your name? I seen alot of different and imbiguos definitions on what Koon Thai can mean. . . Some diriviative of this or miss pronounsing of that ... But here in New Haven, with our downtown being a landmark of freedom ....I find it racest and hurtful. I do not see the irony or even repect the possible meanings in Thai or vietmese. Its untimly always and kinda hurtful. So please dont be offended into a stone. Please consider my request. Ty.

Good spot. Great food! Welcoming atmosphere.

Even though it was not even crowded, we waited almost 45 minutes for our food to come out. The food was good, but not a far cry from any other Thai restaurant around here, and definitely not worth the wait.

Magnificent food. Was really busy and service a little slow but food was worth it! Location is very convenient to Yale Old Campus.

Food was good and not too pricey. Restaurant didn’t have any heat. Still needed to get it fixed or add more heaters.

Best Thai in New Haven and service. Also one of the best places in New Haven to watch people parallel park.

Real pleasant surprise! Spring rolls were crispy & fresh. Satai simply good. Buns & Shumai dumplings were also very good. Spicy eggplant was terrific. All sauces were great

Delicious Food, Great Lunch Special, and friendly Staff

Food is always good.

The owner is lovely and the atmosphere is friendly. The food is great and prices are reasonable, I eat here fairly often

Use to order off Uber eats, but since the price hike my boyfriend and I decided we would go to sit in. The place is cute, everyones nice, cool front window seats, the food is always delicious, and it has the BEST thai tea, weve ever tasted. We recommend the red curry, crispy spring rolls, and the thai tea! Its so good weve never even tried anything else, we order it every single time.Update: recommend the moon dumplings!

Omg, I waited over an hour and half for bubble tea and an appetizer smh. The food was great and the bubble tea was amazing, the environment was beautiful and clean, but I the wait was just not worth it. If the ever become fully staffed I may revisit.

Place was amazing and the food was delicious. Definitely coming here more often.

Customer service was wonderful and food was excellent.

Everything gluten free is clearly marked and the waiter was had great recommendations, but I honestly all of it would have been great.

Food was decent, but it is clearly not intended to be a sit down restaurant. Weird service, the bathroom overflowed while we were there. Good take out, but would not recommend eating there.

Amazing thai place they have lunch menu too.

The food was good and the servers were very friendly and made atmosphere positive. Would recommend to anyone who have an appetite for Thai food

Small restaurant with freshly made Thai dishes. Affordably priced.

Their Pad Thai is amazing. Love this place

Food was decent but waited 30 minutes for a simple dish for takeout that should ha r been 10-15. Would have called ahead but the line was always busy.

Nice small place. The food could use just a bit more seasoning.

Amazing Drunken Noodles. We smelled the food walking past and had to go in. Owner was out hostess and she was very nice. 5/5 would chow again.

Best thai food in town! Love itMost recommended

The massaman curry is delicious!!
