This season's contestants head to Las Vegas where they participate in the signature dish challenge; the winners of the challenge ride on the world's tallest Ferris wheel while the losers peel 50 pounds of shrimp and 1,000 pounds of potatoes.

The teams have 20 minutes to see which team can produce the most shrimp dumplings; rapper The Game attends the dinner service.

The blue team gains a new member; the team that wins a grocery spelling challenge spends the day flying in a stunt plane, while the losing team makes sangria for dinner service; VIP guests include Thomas Ian Nicholas and Omar Benson Miller.

The contestants pair up and prepare three main dishes, each with one of the following holiday themes: July Fourth, Mardi Gras and Cinco de Mayo; challenge winners are flown to Santa Inez Valley, where they blend their own wine.

Grammy-winning guitarist Steve Vai performs; the contestants must create unique dishes with a limited number of ingredients; the winning team plays a game of paintball while the losing team is faced with delivery day at the kitchen.

The teams can only have one chef in the kitchen at a time as they prepare three entrees, each with a different protein; actress Lainie Kazan and comic Bill Engvall are guests at the dinner service.
