"Chicago’s most ubiquitous pizza chain is also one of its finest. Opened in 1971, Lou Malnati’s has helped spread the popularity of deep dish across the city and country. The Malnati clan claims to have had a hand in the dish’s creation and its signature “Malnati Chicago Classic” — sausage, cheese, and tomato sauce on a special butter crust — still sets the standard for an excellent pie. Lou’s also has some newish menu items like a lower-carb sausage crust." - Ashok Selvam, Eater Staff
