This restaurant draws a diverse crowd due to its chef and the menu items. They will prepare food at "diferent spice levels" and when they say very hot, believe it. Mild is a good start here and most dished have enough flavors to please most palates. Have take friends from out of town here and they too have enjoyed the... More

I love finding the diamond in the rough, when it comes to small restaurants. This was good, but not exceptional. First of all, some reviewers spoke of the neighborhood. It's a bit rundown, but not "rough" like inner city Chicago. Get over it. This is truly a mixed review. The food went from excellent (spring rolls) to so-so (curry). The... More

We were recommended this place by word-of-mouth, and had it not come as a recommendation, we may not have walked through the doors, as the outside of the building is in need of some attention! However, upon entering the building, it is beautifully decorated and the staff are over-the-top friendly and accommodating. The food was amazing and I would certainly... More

Ordered #40 from the menu. There were only 7 people in the whole place. When the food came it was absolutely cold - broccoli refrigerator soggy cold. I have no clue when it was made and reheated in the microwave. Scary thought! Sent it back. They put it in the microwave and brought it back out. No apology. No alcohol.... More

This is the best restaurant I have ever been to. I go to this place at least 3 times a month. the staff is super friendly. I recommend the coconut chicken, chicken fried rice, fresh rolls, shrimp in a blanket, and the mango sticky rice. If i could i would definitely order one of everything on the menu.

Great variety, huge menu. Service is awesome. Fast turn around on food. Not the best Thai food ever, but pretty good.

We have been eating at this place when we can for the past 10 years. It has never disappointed. I have eaten Thai on four continents and around the US and this is one of the best. Apparently Phil Jackson recently ate here, one day before we did! We live two hours away, so we try to make a stop... More

Pad Thai and fresh rolls are my favorite but everything is good. You can't go wrong. Ba-Mi-Phat is always on special as it should be.

This little restaurant was referred to us by a local and when we arrived we instantly had second thoughts. But once inside, we fell in love with the place. This is true authentic Thai and the food is excellent and the atmosphere is fun. While not a "fine dining" experience, the family that owns the restaurant are a pleasure to... More

This was one of the best restaurants that we had tried while traveling. There was nothing fancy about this place when it came to decor but it was the most affordable, best tasting food I have ever had. We had tried 3 appetizers, 4 entrees and shared a dessert and the total bill was still under $60.00. We could not... More
