I don't know much about Thai food, but I have to say what they serve at the Smiling Banana Leaf is absolutely delicious. I've had the sweet & sour entree with tofu and the pineapple curry also with tofu. Soooo good. The second time I visited my tofu could have been just a tad bit crispier, but the meal over all was pretty delicious.
It is small and the outside and inside decor does leave quite a bit to be desired. As some others have warned, watch out for the spiciness! My boyfriend ordered his meal at a 7 (out of 10) and his eyes were watering! His entire face turned red and he finished off two glasses of water by the time he was halfway through his meal lol! He did very much enjoy it, though.
I have only eaten at one other thai restaurant in Pittsburgh, but this one blows the other out of the water. It is also BYOB, which I have not partaken in, but keep that in mind!
