Bankok Balcony never disappoints me. Been there a couple of times, and it's lived up to my satisfaction. We frequently visit Silk Elephant too, I cannot see much of a difference taste-wise between the 2 restaurants, especially when you compare their curries.
My favorites are the red curry, the pad thai, the thai fried rice. Recently we tried the fried fish in chilli sauce, it was a bit pricy (18$) but the fish was very nicely cooked and tender&delicious to taste. I am also a fan of their thai iced teas.
I like the seating area, the ambience is trendy as well as casual. Overall, a really good Thai restaurant in Squirrel Hill.
