When I lived in Pittsburgh, I grabbed take-out here on occasion only b/c it was right next to my apartment and very convenient if I needed to eat a late dinner coming home from school. I've tried a few noodle dishes and rice dishes and they're all very "meh". The larb was not even close to authentic larb - it was basically a green salad with ground meat. Additionally, this place is pricey for what you get.
Very uninspired and nowhere even close to "Best 10 Thai restaurant in the US" good as the sign they keep outside says. If you're looking for a Thai restaurant close by, Noodlehead is a half-mile walk away.
2 stars are for the service (the people there seem friendly enough, at least the waitresses up front) and location.
