I love Thai food, my favorite in Pittsburgh is the Smiling Banana leaf in Highland Park, this is a close second. I have been here 2 times for lunch. I have eaten on the patio both times which feels like you are in a beautiful tropical garden nowhere near Pittsburgh. I had the Pad See Ew and the Rat Na/Lat Na/Lad Na. The Rat Na is not on the lunch menu however the chef was nice enough to make it since they weren't super busy. I do have to warn you that they do NOT mess around with spice. I normally get a 7 at most place, but at Nicky's I get a 4. I got a 5 the first time and needed extra napkins because my nose kept running. So please be mindful of the spice levels here. Overall I think this is a wonderful Thai restaurant, great service, and delicious authentic Thai.
