Loogie's Ristorante is an Italian restaurant in South Park owned by Loogie that appeared in the Season Four episode "The Tooth Fairy Tats 2000".
Background
The Boys are taken to Loogie's Ristorante after being caught by a group of kids trying to steal teeth like them. While there, they talk to the kids' boss Loogie himself, who explains that stealing teeth from kids is much more complicated and requires more planning. He then threatens them, saying they can either come work for him in the tooth trade or he can cut off their penises.
Later on, one of the ADA employees named Tom Foley confronts Loogie at the restaurant, where Loogie pretends to be an innocent child to trick Foley so he won't get in trouble for being part of the tooth trade.
