Old Forge style pizza is a regional variant unique to the Scranton area — rectangular, double-cheese, served by the tray rather than the slice, and noticeably different from anything else in the United States. A red pie has tomato; a white pie does not. Half a dozen institutional pizzerias in Old Forge village have been serving it for decades.
Salerno's, Revello's, Arcaro & Genell, and Brutico's are the long-established names. Each has its partisans, and the differences are real but subtle; pick one and order a half-and-half tray (half red, half white). The drive from downtown Scranton takes about ten minutes.
