Last but not least, pizza has been around in the United States for centuries with first pizza establishment in the US opening in 1905 at New York's Little Italy. Most towns and cities in the US has its own trademark pizza. For example, Chicago has its own deep-dish pizza. Detroit has its own unique twice-baked pizza (with cheese all the way to the edge of the crust), New York has a variety of different pizzas, and New Haven style-pizza is a thin crust pizza that does not use cheese unless the customer asks for it as a topping.
