This is quite simply the best Thai food in Pittsburgh.  I have been to all the other Thai joints in the city, and this one is the best.  The food is consistently good and cheaper than many of the other places.  The curries are nicely done.  The pad Thai is excellent (although I prefer the pad see ew).  Tom Kar soup is awesome.  \nService is prompt, friendly, and efficient.  The ambiance may be a little lacking, but the food more than makes up for it.  \nAlmost forgot to mention that it is BYOB.
