Spencer Alben: On Arthur Avenue, also known as New York City's real Little Italy, you'll find the appropriately nicknamed King of Mozzarella, who, accompanied by his son, churns out the best mozzarella and Italian deli sandwiches this side of the Atlantic.

Customer: Been coming here for about 20 years, and it's the best Italian food on Arthur Avenue, best mozzarella I've had, even all across the country and all across the world, there's not better mozzarella than this place.
