Similar to traditional Neapolitan-style pizza and baked in a coal-fired brick oven, New Haven-style thin-crust apizza ("ah-beets") originated in the 1920s when Frank Pepe opened his first pizzeria on Wooster Street. When Frank’s nephew Sal Consiglio opened his own place, Sally’s (Frank Sinatra's favorite), on the same street, a legendary rivalry was born. After those restaurants were joined by Modern Apizza in the 1930s, New Haven took on a destination status, and today pizzerias like Da Legna, BAR and Grand Apizza carry on the tradition. In New Haven, mozzarella ("mootz") isn't standard so make sure you ask for it. https://www.eater.com/2014/3/18/6264277/the-definitive-guide-to-new-haven-pizza
