When it comes to pizza, there are really only two great cities: Naples and New York. This weekend, the two pizza capitals are going head-to-head at the first annual New York Pizza Festival in the Bronx’s Little Italy. There, pizzaioli from six Naples restaurants will serve slices alongside 12 New York City pros — and 11 well-intentioned pizza chefs from other parts of the country.

“These guys are considered the best in the business,” says Fred Mortati, president of the Naples- and Florida-based Pizza Academy Foundation, which organized the festival. And though it’s not an official competition — just an occasion to eat copious amounts of pizza from the best joints around the world — one can’t help but pick sides.
