This old-school pizza shop knows a thing or two about pies, and locals swear by the place's deep-dish crust, which showcases all manner of toppings. Try the "Lou," named for the restaurant's founder. It includes fresh spinach, mushrooms, sliced tomatoes, and mozzarella, romano, and cheddar cheeses. The "Deluxe" is a great value: cheese sausage, mushrooms, onions, and green peppers. Leaving Chicago? Don't worry – pizzas can be shipped overnight to most cities in the US!
