Iron Chef Alex Guarnaschelli makes her triumphant return to Flavortown Market by taking on fellow culinary greats Rocco DiSpirito and Brian Malarkey in one of the most twisted competitions yet. As soon as these all-stars begin shopping for their hometown favorite, Guy Fieri announces the store is closing. Then, Guy hits them with his new swap wheel, which determines whether they have to swap stations, ingredients or places with the judges! In the second round, Guy tells them to swap dishes, turning the burger and fries ingredients they shopped for into a high-end dinner. The chefs continue to swap till they drop, and ultimately the winning chef earns an automatic $20,000.

Guy Fieri invites two powerhouse culinary duos from Los Angeles and San Francisco to prepare three-course feasts designed to prove which city's food is best. First up, the teams must make a 15-minute cold appetizer and 30-minute hot appetizer featuring iconic food items from both cities. Then, in a game inspired by each city's legendary sports teams, the chefs must score footballs to decide how many ingredients they can include in their regional entrees. The city team with the highest combined score wins $15,000 and Golden State bragging rights.
