a visit to chicago helped me clarify the basic types of pizza that are lumped into the "deep dish" category. the basic deep dish style is a bowl-style crust, where the bottom and high sides are relatively equal in thickness. another variety adds a layer of dough on top of the cheese - it's called stuffed pizza. finally, pan style is (like the others) cooked in a pan, but with a thicker crust, shorter walls around the edge, and caramelized cheese around the perimeter.
