Four GGG winners return to Guy Fieri's Flavortown for a chance to take another crown in one big round! They must make a winner's dinner complete with an appetizer and entrée in a non-stop hour-long battle. First, Guy flips a coin to determine whether... (more) they must shop only the odd aisles (no fresh proteins) or the even aisles (no fresh produce). After the chefs deliver their appetizers, Guy flips another coin to determine whether their entrées must include an extra item under $5 or over $20. The chef who makes the highest-scoring winner's dinner will shop the market for up to $20,000
