Una Pizza Napoletana on the Lower East Side has been named the best pizzeria in the U.S. by the Italy-based website 50 Top Pizza. 

The rankings are based on the quality of dough and ingredients used for toppings. Factors such as service quality, wine and beverage offerings and overall customer experience were also considered when coming up with list.

The owner of Una Pizza Napoletana, Anthony Mangieri, joined anchors Rocco Vertuccio and Shannan Ferry Sunday morning on NY1 to discuss his pizzeria.
