First things first, "Chicago" style pizza is not pizza, it's a gimmick. Some restauranteur came up with a gimmick and it caught on. Is it Italian? Even New York Pizza isn't considered true Italian. Thin dough, olive oil, fresh tomato, whole milk or buffalo mozzarella, and fresh basil. That's a true Italian gem.
Let's dissect a Chicago pizza, why does the crust taste like biscuit dough? 'Nuff said. Sausage between the layers of dough? So you steam the sausage? Sounds disgusting when you think about it. Fresh tomato and any other topping and a sprinkle of romano on top. Basically a Chicago style pizza is a quiche, minus the eggs of course. It's American, and Chicago can have it.
Four stars for little chicagos regular pizza!
