I would have to put Angelo's in the upper 10% of pizza joints here in Pittsburgh. They make you're standard medium thick crust, heavy cheese, heavy cooked sauce, heavy toppings pizza. That being said, they do each of those components better than most pizza shops. The crust is crispy and chewy and actually tastes like something, the cheese doesn't taste like cheap pre-shredded junk, and the sauce is flavorful enough to stand up to the heavy handed cheese and toppings.
Oh, and the pizza tastes great cold the next day so go ahead and order a little more than you need!
