They May Be Infringers, But They Have Damn Good Shakes CNN has a report about a trademark dispute between Chicago's Billy Goat tavern, which uses the slogan "Cheezborger, Cheezborger," and the Florida-based chain Cheeburger Cheeburger. The Cheeburger Cheeburger in Richmond has an excellent Cotton Candy milkshake. Haven't found one of their restaurants up here in DC yet, though.
