As pizza goes outside the I-95 NY corridor, I haven't generally been very satisfied. Pittsburgh in particular seems to lack good thin crust NY style pizza. Village Pizza is the closest I've found. The slices are too small but the dough is really good.
For a while they didn't deliver but now they do. Apparently they are now called S Aiken Bar & Grill or something, an attempt to branch out beyond pizza I guess. I know the bar is popular. They have burgers and stuff now too.
