Mayor Guy Fieri declares Seafood Day after Flavortown's fleet of fishing boats returns to harbor with a bodacious bounty. The reigning champ casts their net for even more riches against Mediterranean master Cristina Topham and Southern comfort-food chef Lambert Givens. After a fish-filled food fight, judges Jonathon Sawyer and Michael Voltaggio will decide which seafaring chef will reel in up to $20,000 and who will return to shore empty-handed.
