In 2008 we loved it. Fabulous and fun server and it was fun watching all the antics being pulled at the other tables.
2009 hated it. Food was still very good, but the service was awful. No antics, seemingly from any server, but our waiter was terrible. No drink refills, wouldn't clear plates to make room for new plates, would walk right past our table. The manager actually came over to ask how our server was working out, so he got an ear full, but even then the manager didn't offer to get us drinks (we were a party of 6 and everyone's glasses were dry for the entire meal.)
As others have said, it is an extremely loud restaurant and both times the wait was very long, even with ADR's.
