Great place for a simple classic Thai meal. It's family run so it's nothing fancy but serves all the basics. Excellent lunch spot with great prices. Great quick service for the business diners but they don't rush you if you want to linger. Spicy options on entrees runs from 1 - 10 and you pick it the way you like... More

This is one of my favorite places to eat in Manassas. The food is always really fresh and the portions are generous. The customer service is usually pretty good and they are willing to make changes to dishes for allergies which is very helpful. I have never had a bad meal from here.

So we had an awesome lunch the food. was served quick and hot here,and the wait staff was on top of it and they left us sit sit outside for hours outside even after they closed so we can socialize with friends. Great energy by both staff and the atmosphere

Boring atmosphere. Boring staff. Boring drinks. Better than average menu choices but the food is still boring. I've been here a bunch of times and kept coming back in the hopes they would one day magically come to life. Alas, it never happened. There are other, better options for great Thai food.

I cannot lie, I like Thai food and this place was very good at reminding me that I like Thai food. Only ate here once, but there wasn't anything to make me think that any time I'd come back wouldn't be just as good. Definitely would come back.

I've patronized this restaurant for many years and never been disappointed. I think it is family owned which shows in the care and detail the food embodies. Although I have never had a bad meal here, my most recent choice was the Noodles with Shrimp - a clear but tasty broth packed with rice noodles, and adorned with shrimp and... More

This place is small, quaint, and a bit romantic in the back tables. It's not unfriendly for kids or families, but it's just not designed to make them comfortable. The food is great. The service is hit or miss and usually slower than other Thai places. If you're not in a hurry and want a table for 2-3, then I'd... More

The place is just too small to be call a restaurant. We got there and was seated and I was facing the bathroom well that's a no no for me. We asked to be moved and the waitress said the order had already gone through with the table number. I told her we are the only people in the restaurant... More

I go to this place every time I visit Manassas. The taste of their dishes is wonderful. The size of the dishes are just good. Not too much, not too little. Probably the best affordable dishes in the area.
