It is no longer in business. It is defunct. It is so longer a going concern. The chairs are up and there is a sign in the window that says closed on Saturday evening.

I enjoyed this restaurant food especially the satay for only $7. Great price! but the atmosphere is not so hot if you are looking for the experience. I recommend the food though

They have the best Thai food in Gaithersburg. The service is always good. Unlike some local Thai place hot really has some heat to it. It also has the advantage of being a nice quiet place for a conversation.

Much better Thai food served in Germantown, MD. Although the food is not bad, the restaurant is dreary and outdated with no atmosphere. Even the wait staff is dreary with black clothing and black skirts to the floor, which make them look like nuns.
