Best Thai in Pittsburgh hands down.
I've been here several times with my girlfriend and I've had a different thing from the menu every time I went and have yet to be disappointed. Their Pad See Ew is the best I've had anywhere and their various curry dishes are top notch. Service is great and both the indoor and outdoor seating are very quaint and not overdone. My only issue is that prices tend to be a bit higher than other places I've seen for Thai, but if you're in Pittsburgh and are looking for a good Thai place, don't pass up Nicky's.
