Billy Goat owner Sam Sianis has used "cheezborger, cheezborger" to advertise his local restaurants since the mid-1980s. The phrase was made famous by comedian John Belushi in parodies of Greek restaurants on "Saturday Night Live" in the 1970s.

Cheeburger Cheeburger Restaurants Inc. has been in business since the mid-1980s. Sianis didn't care about the Cheeburger Cheeburger chain of 32 family-style restaurants until they announced plans to open in suburban Glenview. Attorney Raymond Niro told the Chicago Tribune that Billy Goat is suing in federal court, requesting a preliminary injunction to keep the Florida restaurant out of Sam's backyard.
