I've tried Calzones in many cities in the US trying to match the greatness of my home town NYC/NJ itialian eateries and all fall short except for Napoli's. Infact Napoli's calzones beat many if not all from home. Their gourmet pizza's are exceptional as well. A must have in San Antonio.
Pros: Great food, great people, good prices
Cons: Located in a strip mall hard to notice or stand out
