This is my second review of this place because I am just blown away every time I come in. How is this place not packed every lunch and dinner time is beyond me. The quality of the food and portions here are outstanding. If you're looking for the best Chinese in O'Fallon (I'm originally from North County) this is your spot. Pricier than your average but it's not just average. read more

Bayon Bistro - Beef Fried Rice - Asian Fusion Near Me - O'Fallon, Missouri

Our favorite place to eat! Staff is so friendly and food is AMAZING!! We make sure to go every time we are in town!

I stopped by for a quick lunch waiting for doctor's appointment. I ordered Green Curry with vegetables and miso soup. The miso soup must have been pre-made and ready to be served because the waitress brought the soup within a minute. The soup was flavorful. The Green Curry was served quickly (before I 1/2 way finished the soup). While the curry was more soup based than I expected, the rice mound added rounded out the dish. The curry was flavorful, but not really hot (as warned by the waitress). Overall- the meal was what I wanted. The price and the strip mall location was a little let down. This was not bad for a lunch special. read more

The service was wonderful. The food was great. I had the egg noodles with chicken. I don't do well with spice & this had a little spice. The portions were very large. The crab Rangoon had crab in it! For $14 it will be 3 meals. Fresh ingredients & the lunch special is a great deal. I would recommend trying this small business! read more

Bayon Bistro - Egg noodles with chicken. I had the lunch special & it was huge plus 2 crab rangoons. Very tasty! - Asian Fusion Near Me - O'Fallon, Missouri

Food was delicious. We got the crab rangoon. Comes in orders of 6 and a big bowl of sauce. Right now they have a special going on: buy three rolls get one free. We got the volcano roll, anchor thom roll, spider roll, and crunchy roll. They were pieces of art! Our total was $55, if you compare that to sushi ai, the price is the about the same and you don't leave feeling like a glutton. read more

Bayon Bistro - Mongolian Beef (but I asked them to hold the mushrooms) It had a delicious spice to it. The beef was nice and tender. - Asian Fusion Near Me - O'Fallon, Missouri

This was our first visit. The restaurant has a nice aesthetic and the service was perfect. We sat at the bar to watch the ballgame and the bartender was great! We ordered seaweed salad, crab Rangoon, rainbow roll, tunle Sap roll, and cold Sake. As far as the food goes, the presentation was beautiful. The seaweed salad and crab Rangoon were exactly what you would expect in terms of taste. The sake was really refreshing. The rolls both had a sweet sauce on them. Personally, not my favorite. The tunle sap roll Was my favorite item. Besides the tinge of sweet, the flavor profile was superb. The issue was that the rolls weren't wrapped tight enough, which made it challenging to eat with chopsticks. read more

Very disappointed. Potstickers were burnt and fried rice was stale with burnt pieces in it. Spicy tuna rolls had no spice at all. We ordered takeout and didn't receive the drink nor any utensils. I ordered take out at 8pm on a Friday night so I would never expect the food to be so stale. So disappointed, especially given my order was so simple. read more

We finally tried the restaurant under the new name/management. Very clean and nice staff. Food came quickly and great sized portions. The spring rolls were delicious. I enjoyed my pepper steak but we did not like the sweet & sour chicken. Both the sauce and texture of the chicken. The food seemed very similar to the previous establishment. Worth trying. read more

Located in a quiet neighborhood area in Winghaven. Nice ambiance with bamboo stick dividers, photos, fish tanks, etc. Nice wine bar and sushi bar area to the left of the restaurant. Food: * the Cambodian street wings * 2 White Tuna * 1 Roll (Tunle Sap Roll) * Spicy Tuna Handroll * Shrimp Tempura Handroll Everything was good! My favorite was the Tunle Sap Roll. Loved the Jalapeno and Cilantro and how it balanced well with the Yellowtail and the sauces in the Roll. Constructive criticism: 1) Tuna in the handroll needs to be chopped up better. Some of the tuna were smushed up, and some were chunky. It was questionable! 2) I personally didn't have any issues, but there is an opening at the bottom of the roll that can fall apart easily (for people who have difficulty using chopsticks). I need to come back to try out their entrees (rice, curry, and noodles). Good service Convenient parking Clean restrooms Baby changing station in Women's restroom read more

I've been here in the past and the food was ok however, last week I ordered to-go and got home to notice my salmon was burnt. Would suggest checking your food, as with most restaurants, before leaving. The color is not from the teriyaki sauce, it was burnt and crunchy on the top and bottom. read more

Bayon Bistro - Teriyaki Salmon - Asian Fusion Near Me - O'Fallon, Missouri

Sign stated closed due kitchen fire. Been shutdown for a month. R.I.P. Only Asian restaurant that played country music.

Fresh, hot, and delicious. All of our food was very good. The Cambodian Street wings were a nice start. They were fresh and crackling from the fryer, and came with a dipping sauce that was citrusy and peppery. The sauce really punched up the flavor. The teriyaki sauce had a nice dense flavor for the entrées. The huge fillet of salmon was tender and flaky and had a great crispy edge to it. read more

Love this restaurant - so consistent and the staff is great!! They have the best sushi and fried rice. The owner - she is awesome - remembers us and what we like. Highly recommend this restaurant - best Asian food in O'Fallon/St Louis! read more

My wife saw a write up on this restaurant recently and we decided to give it a try. The food and service were absolutely outstanding. If you like spicy, be sure and let them know; they can certainly accommodate your taste buds! We loved it and we'll be back very soon! read more

The service was good. The ambiance is much improved from the prior Chinese restaurant but the food was not to my liking. Many taste of classic dishes where foreign to me. Their cashew chicken tasted like Chicken McNuggets from McDonald's. Teriyaki chicken was super dry. My wife and I were very disappointed. I know many of you may like the food and I'm glad for that. But as for my wife and I, we won't return. read more

Great little spot with wonderful tasting food. Everything we had was great. Quick and efficient service with some excellent menu. read more

The offerings here are SO good. Owner is very hands on. Visited again on a Saturday, prime dinner hours. Such good food and incredibly friendly service and staff. Where y'all at? If you haven't eaten here, where you at? Recommended read more

This place is amazing. They seem to serve cuisine from all over Asia, they serve amazing sushi. But the best thing hey serve is native Cambodian cuisine. The food is delicious in fact if you like Thai food you'll love Cambodian food read more

Holy cow, what great flavor! I went with my mom and my daughter for an early dinner on a Wednesday afternoon. It is a new place and as you can imagine we were the only ones in the place. Our server was very helpful answering questions as I don't think Missourians are very familiar with Cambodian/Asian fusion. While the crab Rangoon was average (it could use more crab) the dipping sauce was really good. Not the typical sweet red sauce. The pot stickers were phenomenal! They were perfectly crispy and the ponzu had awesome flavor. For dinner my daughter had a beautiful California roll. My mom had the orange chicken which had gorgeous chunks of fried white meat chicken and veggies in a flavorful orange sauce. I had the Cambodian noodle soup with chicken. Think Pho but spicier. The broth had an amazing green curry spice flavor with rice noodles, bean sprouts and green onion. Perfect on a cold January day. The decor is inviting and the sushi bar looks like a great place to have a drink with a few friends. The bathrooms are also clean which is a bonus. I can't wait to go back and try a few other things. read more

I don't care how good the food is, the service is awful. I watched a woman get thrown out of the restaurant for no apparent reason. We won't go back. read more

The food was expensive (27.95 for shrimp fried rice and spring rolls). Extremely excellent food. Unfortunately 1 server, a bit slow & unbelievably rude. Won't be back unless it's to go. read more

Real highlight for me is not what I have posted in this photo. I also ordered Springfield Cashew chicken but forgot to take a picture of it. I have been trying to find cashew chicken for almost last few years in St Louis but nothing is close to what you get in Springfield. Atlast, my search ended here. They have real Springfield Cashew Chicken and it was awesome. I liked all their rolls but except Bayon roll which I felt too oily. Overall, I had a great experience. I am sure I will visit this place again just to taste their Cashew Chicken. read more

Really like the food, but this is the second time we've done take out, and their to go containers are awful. The sauce has spilled out of the bag and onto everything by the time we're home. read more

The female owner is extremely rude. She yelled at one of the servers because she was speaking with a customer and then told the customer not to speak with her server unless she was ready to order. We won't be back. read more

the woman that owns this place is a total lunatic. my husband and I dined at this place all the time. We really liked the food. But When we walked in tonight, she started screaming at me and accused me of writing a bad review about her on Yelp. I swear, it wasn't me who wrote the initial bad review, but I'm sure the heck going to write one now! She literally kicked us out of the restaurant. there was one table of customers in the whole place, and yet, she kicked out a good customer. BTW... I had actually given the Restaurant a good review on my subdivision's FB page a while ago... i have never been treated so rudely and I did nothing to deserve it. read more

We've truly enjoyed dining in this place since it has opened. My husband and I have been here well over 5 times and have tried multiple items on the menu. The Cambodian Street Wings have such a unique, addicting flavor and they are super crispy! We've had the Chicken Fried rice, Beef Mongolian Stir Fry, Kuy Teav, and Green Curry and all of these dishes were delicious. We love that you can pick the spice level of the dish as well! I can't wait to try the sushi. It looks beautiful every time it passes by our table! read more

Some of the best sushi in the area. Large variety of entrees that all have been good so far.

food was great especially the sushi,Cambodian beef soup and calamari salad.service was top notch Nyta is our favorite server. Sieron is great as well but she's in the kitchen most days. Chef Dara is well known in the area. There is also Korean barbecue but it's not on the menu. read more

One of my favorite new restaurants in the area. Have had it many times now. The general chicken and Springfield is the best I've ever had. The fried rice is also very good. The way they fry everything is perfect and they get it right every time. Will be a regular! The chicken is crack. read more

Delightfully fresh food and friendly service with a great happy hour menu. Can't wait to go back. So glad to discover this gem near my house. read more

Excellent Springfield style Cashew Chicken!! Closet I've had up here, without the trip to Springfield!

10/10 We absolutely loved everything we had here! We couldn't believe the flavors. They tasted so fresh and made from scratch. We had the crispy roll, orange chicken, Mongolian fried rice, and I can't remember the name of mine, but he said it was the Cambodian version of pad Thai I believe...so insanely delicious! We will be back soon! read more

Authentic. Hot. Service was excellent. Atmosphere was enjoyable. Will definitely visit again and I highly recommend.
