Chicago-style pizza
Chicago-style pizza is pizza prepared according to several different styles developed in Chicago. The most famous is deep-dish pizza. The pan in which it is baked gives the pizza its characteristically high edge which provides ample space for large amounts of cheese and a chunky tomato sauce. Chicago-style pizza may be prepared in deep-dish style and as a stuffed pizza.
Deep-dish pizza.
According to Tim Samuelson, Chicago's official cultural historian, there is not enough documentation
baked in a well-oiled pan to a chewy medium-well-done state that gives the bottom and edges of the crust a fried or crunchy texture. 
The difference between Detroit-style pizza, Chicago and New York styles is the crust, which is extra thick and very crispy on the bottom. Some parlors will apply melted butter with a soft brush prior to baking. The resulting pizza has a chewy texture.
