Ate here with my wife and college-aged son during a recent visit to Pittsburgh. Decent parking. Easy to find.
The good news was that our food was really, really good. The bad news is that we ordered too much food :-)
Ordered pepperoni roll, gnocchi with meat sauce, and large thin crust pizza with mushrooms and italian sausage. Meal also came with salad and garlic bread. Everything was terrific! Pepperoni roll was cheesy with a good pepperoni-to-dough ratio. Gnocchi had good texture and the meat sauce was tasty. Pizza was my favorite. Really, really awesome crust that wasn't as thin as you might find at well-known pizza chains.
While I love Primanti Bros... Juliano's is a great alternative if you want something other than a great sandwich.
