Famous Roio's Pizza is named after the town of Roio del Sangro in Abruzzo, Italy. The owner and founder of Famous Roio's Pizza returns to the location where he began in the pizza business in the 1970s. Mario DiRienzo and his brother Lamberto opened their first location in August of 1973. Their pizza quickly gained notoriety and was highly acclaimed by many food critics. After a hiatus of more than 30 years, Mario has decided to return to the location that he made famous many decades ago. People may not know the name that is now displayed at the corner of 6th Avenue and 11th Street in Greenwich Village, they will however, undoubtedly recognize the taste. For many it is a bite of nostalgia, for those unfamiliar, it will be a taste of why New York is known for its pizza.
