The 5-8 Club's signature menu item is its Juicy Lucy cheeseburger which consists of cheese cooked inside a patty of Angus beef.[1] There is contention between the 5-8 Club and Matt's Bar, another Minneapolis eatery located 23 blocks north of the 5-8 Club on Cedar Avenue, about which establishment invented the burger.[5][6][7] According to the 5-8 Club, they developed the dish in the 1950s.[7] The version served by the club is spelled Juicy Lucy, while the Matt's Bar iteration omits the letter I, resulting in a spelling of Jucy Lucy.[5]
