Papa's 12 Inch is an Italian restaurant featured in Grand Theft Auto: Liberty City Stories. Its specialty is Italian food, specifically 12 inch pizzas. There are two stores located in Chinatown, Portland and in Belleville Park, Staunton Island, just near Aspatria. The Belleville Park branch also has a Freeway and a phonebooth beside the store, wherein Toni Cipriani receives one mission from Salvatore Leone. Unfortunately, both stores are inaccessible.
- The name "Papa's 12 inch", is an attempt at crude humour, implying a 12-inch penis.
- The logo of the restaurant is somewhat similar to that of Papa John's Pizza.
