The Krystal Square Off was the official World Hamburger Eating Championship from 2004 to 2009, taking place in Chattanooga, Tennessee and sanctioned by the International Federation of Competitive Eating (IFOCE). In this event, contestants ate as many Krystal hamburgers as possible in eight minutes.
The Krystal Square Off consisted of a qualifying tour and a world championship. In the qualifying tour, amateur eaters competed with professional eaters for a spot at the world championship. In 2004, the first year of the event, local amateurs Sam Vise and Jeff Hicks defeated professionals to earn a position at the world championship.
