The service-with-a-snarl shtick — a gimmick that peaked in the late '90s, when Seinfeld's "Soup Nazi" was nothing short of a cultural phenomenon — can wear thin in a hurry, particularly if the food doesn't counterbalance the server's indignation. The continuing success of this brusque downtown Hollywood mainstay is testament that it's got the pie to back up the 'tude. Forget about clean eating; things will get messy. Each slice is so epic that it spills onto a second plate and necessitates a fistful of paper napkins that you can only hope will make a dent in the wreckage of grease, cheese, and sauce flying around your person. Your best bet for a good experience: Speak clearly, carry cash, and don't wear white.
