Went because of previous reviews. The spring rolls were good (best part of meal). Ended up choosing the recommended specials. Roasted chicken was greasy and not that good. Other dish was basically a stir fried onion, celery, noodles and a few shrimp and little chicken. The big issue was taste. Neither dish had it. For those who eat Thai frequently,... More

Very small unassuming building that seats 48 people. Nothing fancy but they make up for it with the delicious food. Cashew chicken, wanton soup, pork & shrimp wanton hot pot...all delicious!

The authentic Thai meal was certainly good. Me personally desire and require something the will fill a very large void at times. This particular time when dining here for lunch was one of those moments. My meal here was definitely authentic and good. The communication barrier was at times evident during my visit.

this small, intimate restaurant is a little out of the way, and can be hard to locate, but once there the food, decor, and staff make it more than worth your while to take time to find it.

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.

Thank 202richard
