Thai Cuisine is one of the best Thai places I've been to in the States - finding it in Pittsburgh was a real surprise. The food here is outstanding, and the service is comparable to what I'd expect in a $50/person restaurant, and this place is definitely not $30/plate. With appetizers, Thai iced tea, and two entrees, my girlfriend and I paid about $30.
I highly recommend the cold chicken and sprout salad. Wish I could remember the name of it, because it's heavenly. (...Which probably assumes that heaven looks like Thailand. ...Which would be a nice place to spend eternity.) Thai iced tea is really good, too.
