The challenge facing the 11 remaining chefs: devise tasting menus for a retro-themed high-school prom, with the losing team having to set up for the prom. Then, appetizers and fish bedevil competitors at dinner service.

The 9 remaining chefs create dishes using five ingredients selected at random. The winners visit Las Vegas while the losers peel 1000 potatoes. Guests at the "Family Night" dinner service include Jerry Springer and members of Chef Ramsay's family.
