Sbarro was founded in 1956 by Gennaro and Carmela Sbarro. The couple and their three sons, Joseph, Mario, and Anthony immigrated to America from Naples, Italy. The same year, the Sbarro family opened their first salumeria (an Italian grocery store) in Brooklyn, New York, which became popular for its fresh food and Italian fare. Its original location closed down in 2004. The success of the grocery store led to the opening of additional locations in the New York City metropolitan area. In 1970, Sbarro opened its first mall-based restaurant in Brooklyn's Kings Plaza Shopping Center. One of their busiest outlets was located in the World Trade Center mall.

In 2014, the Fiscal Times listed Sbarro as the worst fast food restaurant chain in America. In May 2015, Yahoo! Food ranked Sbarro as the second-best pizza chain in America, among competitors Dominos, Little Caesars, Papa John’s and Pizza Hut.
