While in Rome recently we were looking for really good pizza from a wood fired oven. "Pizzeria da Baffetto" was rated #1. It was very crowded, so we asked to purchase a beer while we waited. They said no, we just had to wait. So I went next door and purchased 2 beers. We were hollered at several times about not waiting in the correct spot, then they screamed at us for having beers, when our table was ready, one guy said we could finish our beer at the table, the other screamed at us for bring them in. My daughter speaks Italian, so she could understand them cursing at us. We wanted to leave at that point but our friends wanted to stay. The pizza was just average at best, but the service and the way we were treated was totally rude. They even demanded a tip. My advise is not to bother with this place.
If you want really excellent pizza go to "Mariotti" outside of the subway stop at Spagna. Grab a slice of the best pizza outside of Naples.
