Pizza

In 1905, the first pizza establishment in the United States was opened in New York's Little Italy. Due to the wide influence of Italian immigrants in American culture, the US has developed regional forms of pizza, some bearing only a casual resemblance to the Italian original.

Chicago has its own style of a deep-dish pizza. Detroit also has its unique twice-baked style, with cheese all the way to the edge of the crust, and New York City has its own distinct variety of pizza. New Haven-style pizza is a thin crust variety that does not include cheese unless the customer asks for it as an additional topping.
