DEEP dish or pan- 1/2” thick or more. Like…pizza made on biscuits or sliced bread thick.
Done right, the sauce & other toppings with liquid components soak into the bready crust. Even with LOTS of sauce, pizzas like that don’t get drippy.
When I was a kid, there was at least one chain we hit that did pizzas like that. Shakey’s, maybe? But that’s memories from 40-50 years back.
Is Shakey's the one that had the curly straws, a window you could watch them make it through, and maybe even a player piano?
