Pizza is probably one of the most popular foods worldwide. The tomato pies originated in Naples, Italy, but have captured the world by storm. Today, it’s common to see pizzerias and fast-food joints offering hot slices of pizza. Specifically, in the US, states, and cities transformed the traditional pie into their variation. While some argue that NYC has the best pizza, others claim that the Chicago deep-dish pizza is an iconic classic. Regardless of people’s preferences, it’s a fact that the US has its take on pizza. Foodies should pack their suitcases and tour these cities for an epic pizza tour across the USA!

9 Chicago, IL

This pizza is so decadent that it can be eaten like a pie: with large, hefty, thick slices. One of the best things about Chicago-style pizza is, like any other pizza, the way the cheese pulls as a slice is removed from the pie!

Moreover, Detroit-style pizza is known for its fluffy, deep-dish-like crust. Ladles of tomato sauce are topped with sprinkles of freshly-grated cheese and studded with glistening pepperonis.

5 California

The Golden State is just as sunny as its pizza! California-style pizza offers a light, chewy dough (similar to traditional Neapolitan-style kind) cooked in a wood-fired oven. The pie is then topped with fresh toppings, including artichokes, arugula, kale, pesto, and other delicious toppings. More ritzy ingredients—like bone marrow, BBQ chicken, bean sprouts, and pate—are also possible toppings on a California-style pizza. Even avocados (a Californian favorite) can be added to the top of a fresh California pizza. The sky's the limit when it comes to customizing this sunny pizza variety!

4 Milwaukee, WI

Also known as bar pizza or tavern-type pizza, the Milwaukee-style pizza is characterized by its oily, thin, cracker-like crust.

This pizza is distinct because it’s cut into squares instead of a triangular shape. Often a staple at bars or pubs, the Milwaukee-style pizza is a great shareable pie that goes great with a fresh, cold one.

3 New Haven, CI

Charred food may sound unappetizing to some, but that's only because haven’t tried the New Haven-style pizza yet! This special pie is equipped with a thin crust cooked inside a coal-fired oven, giving the dough a slightly charred look. The dough is also noticeably chewy because it’s left to rise for long periods in cool temperatures. However, perhaps the most distinctive trait of the New Haven-style pizza is its simplicity: ladles of sweet tomato sauce paired with gratings of Romano cheese!

2 St. Louis, MO

Who says all pizza are created equal? The St. Louis-style pizza is unlike its American pizza siblings. This pie’s base is a crispy, cracker-like crust made without yeast. The result is a relatively flat, unleavened crust, that's perfect for mounds of toppings. Moreover, instead of the traditional mozzarella, the pizza is topped with Provel, a processed white cheese made in St. Louis (and surrounding areas). To enjoy this pizza, it’s cut and divided into square slices.
