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 Big wheel while the losers peel 50 pounds of shrimp and 1,000 pounds of potatoes.

The teams must create six unique dishes for former sous chef Andi; while the challenge winners spend the night in Las Vegas, the losing team makes a mountain of macaroons; dinner service has the contestants cooking for Andi's wedding reception.

Kris Jenner and Dita Von Teese enjoy duck dishes as one team pulls off a near-perfect dinner service.

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

Dinner sees the 12 remaining chefs serving octopus, steak and lobster, but lacklustre performances from both teams leave Gordon Ramsay far from impressed.

Gordon Ramsay's gruelling chef challenge continues. The ten remaining chefs are challenged to create unique dishes with a limited number of ingredients.
