Regional eating custom

New York slice culture

New York City's pizza culture is built around the individually-sold slice — large-format pizzas cut and sold by the piece from a counter, folded lengthwise to eat while walking ('the New York fold') — a distinct commercial and eating custom from either Naples' whole-pizza-per-diner tradition or a full pie ordered for a table. Slice shops operate as fast, informal, walk-in food rather than sit-down restaurants.
