outrageously good. this place was suggested to us by a couple of taiwanese foreign exchange students as an excellent restaurant. they were dead on.
we tried a few different things. the basil was delicious and fresh. thepadthai was wonderfully authentic and flavorful. the mango chicken yellow curry was borderline perfect. but the highlight of the meal was the mixed seafood in a green curry sauce. it was chock full of fresh, large scallops, tail-on large shrimp, four clams, lobster, and squid. it also had eggplant, shiitake mushrooms, green and red peppers, and fresh snap peas as well. it was so good it literally brought tears to my eyes; so good, the sauce could have been served in a pint glass and drank. this dish was literally the highlight of my visit to pittsburgh.
the menu here is extensive, and the restaurant (from what i hear) is virtually always packed. the ambiance is great as well.
my only complaint, which is very minor and mostly my fault, is i ordered my food thai spicy. i am no lightweight for spicy food, and enjoy very hot meals. so when i ordered my food "thai spicy", i knew it was going to be spicy but had no idea it was going to be that spicy. i was warned by my waiter that it was going to be hot, but o lord jesus its a fire. nicky's has a sliding scale of mild, medium, hot, thai spicy, and extremely spicy so i didn't think it would be too hot to eat. but by the end of my meal, i was sweating from my face down to my chest. be weary!
