Beto's Pizza shared by @eater says: ""Opened in 1953, Beto’s is Pittsburgh’s oldest pizzeria, but it keeps customers coming back and newbies pushing through the doors with its unique twist on toppings. Once the pizza crust, sauce, and first layer of cheese is piping hot, it’s removed from the oven and topped with cold provolone cheese and your choice of toppings, creating a surprisingly delightful contrast of temperatures and textures. Don’t expect a whole pie, though; Beto’s only sells pizza by the cut."" on Postcard
