Hands down my favorite Thai restaurant in Pittsburgh. It's great whether you are eating there or getting take-out, but if you eat in be aware that it's BYOB. You can get a pretty good Thai iced tea though if you're not into alcohol.
The food is reliably good and the portions are fair for the prices. I've always had a pleasant experience dealing with the folks who work here as well. If I had lived in Highland Park I would have eaten here all the time.
