The Top 12 head to Sin City for a team challenge during which they serve 50 VIPs in entertainment and hospitality at Caesars Palace for its 50th Anniversary party. Each guest tastes both teams' dishes and then casts a vote for their favorite dish. The team with the most votes wins, sending the losing team back to the kitchen for a pressure test. It is then up to the judges to decide who heads home. (thetvdb.com)
