Hands down I would say this is the best Thai food in the city of Pittsburgh and probably surrounding areas and maybe a biased opinion but they have really good food.
I like to warn people who go to the location in downtown Pittsburgh the place opens at 11:30 be there at that time if you come later it's kind of odd but you have to watch other people eat while you stand in line for your turn to sit down.
There are other locations there's a location on the North side and there is a location in the North Hills of Pittsburgh the location North Hills of Pittsburgh is a larger location so less stability as the city.
I love this place it's been awhile since I've been there I definitely recommend it.
