Vico, Italy, is well known for its “pizza a metro” or pizza cut by the meter, which was created by Gigino Dell'Amura in the 1930s at Pizza A Metro Da Gigino. Still going strong, the restaurant has taken on the nickname "Università della Pizza," thanks to the quality ingredients used and variety of flavors offered, all prepared rigorously by hand. Run by Dell’Amura’s five sons, this barn-like pizzeria produces kilometers of pizza each day in three huge ovens. Although it seats around 200, you may still have to wait for a table. No reservations are taken.
