Longo said Prince Street uses a New York WaterMaker system to replicate the characteristics of New York City water at its locations outside the Big Apple. The goal is to make the pizza feel as close as possible to the original Prince Street shop, according to Longo. "The idea is that when you walk into a Prince Street Pizza, you should feel like you walked into a pizzeria in New York City," Longo said. Known for its Sicilian-style square pies and pepperoni-loaded slices, Prince Street sees room for further expansion. Prince Street is now focused on building a larger national footprint.
