Guy Fieri invites eight of the winningest chefs in GGG history to compete in a five-part tournament full of his toughest games and wildest surprises. The tournament champion will be crowned the GGG Greatest of All Time and receive an incredible $70,000 prize. First, Guy tells the unsuspecting chefs over the PA system that the games have already begun, giving them 30 minutes to make their best handheld dish using only the ingredients they can carry to their stations in their bare hands. The bottom three chefs go to a sudden-death elimination round, where they're given just 20 minutes to make a full Sunday supper. Part 1 ends with two chefs being eliminated!

Six all-star chefs are still in the running for the title of GGG Greatest of All Time and the $70,000 prize. Guy Fieri surprises the competitors with double wheels that pick their dish and game at random. First, they must make a vegetarian dinner while observing the express lane's strict ingredient limit. In the sudden death elimination round, the bottom two chefs must make their best noodle dish using only ingredients from the even aisles of the store.
