Guy Fieri invites four of his favorite Diners, Drive-ins, and Dives seafood chefs to make some waves in Flavortown Market. First, they must make a regional dish using the fish they catch in their fly-fishing net, plus any other ingredients they can cram into the net in a single shop. Then, Guy invites his DDD chefs to prepare a seafood spectacular, but instead of digging for clams, they must dig in the sand for canned seafood to use in a fresh shellfish dish. The chef who sails through both challenges will get to search the store for hidden treasures worth up to $20,000.
