New York City is the most competitive pizza market in the country. Millions descend upon the city daily in search of the best slice, and national chains together account for less than one out of every ten pizzerias. With a slice shop on every block, competition is minutes away. Differentiation isn’t strategy - it’s survival. But if your shop can rise to the top, the upside is limitless. Your pizzeria becomes a bucket-list destination for tourists, a local institution with lines around the block, and a springboard for global expansion. No one behind the counter has ever talked shop on the record - until now. We spoke to legacy institutions, big names, and newcomers across the city. They’ll let you film but almost no one, especially the old-school Italians, would talk numbers.
