Definitely the best Thai food I have had in Pittsburgh.
I have been many times to Nicky's. I love the curries there and I love them hot. But I definitely learned my lesson the last time I went. I usually get a number 7 but decided to up it to an 8. Bad choice. I couldn't eat more than a few bites. It was sooo spicy. There must be a big jump in spice levels between 7 and 8.
Also, make a reservation! It is usually packed!
Bonus: It is BYOB!
