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!

Five chefs remain in the competition for a $70,000 prize and the title of GGG Greatest of All Time. A double spin of Guy Fieri's dish and game wheels determines that the chefs must make a champagne brunch using only 8 lbs. of ingredients. In the elimination round, the bottom two chefs fight for their survival by creating a seafood feast featuring the mandatory items on Guy's grocery list.
