Here's a pic of the local regional style ("Ohio Valley Style")
Beto’s in Pittsburgh serves pizza this way. My friend and I went there it was down the road from our hotel. We figured we would get a pizza to go and eat back at the hotel before the game. We should have known something was off when we asked for a large pizza and they were like “we sell by the slice or tray”. Nothing like opening the box when you get home and you see a mound of uncooked toppings.
