In 1956, Carmela and Gennaro Sbarro opened the doors to their Italian salumeria in Brooklyn. Carmela “Mama” Sbarro made pizza slices for shift workers looking for a quick meal. Her slices were so popular that they soon opened a second location focused solely on pizza. Since then, Sbarro has brought the best pasta, salad, and of course the XL NY slice to 630 eateries across 28 countries.
