This week's challenge takes place in the HELL'S KITCHEN "Jungle," where the contestants must create a dish using exotic meats - Boar, Venison and Elk - that were eaten by early humans. Each team will use a spear to hunt for five ingredients to prepare as sides for their dish. Gordon invites special guests Chef Jon Shook and Chef Vinny Dotolo (Animal, Son of a Gun, and Trois Mec restaurants) to help judge the challenge. Later, during the dinner service, Goo Goo Dolls lead singer John Rzeznik is a guest at the chef's table, causing a change in momentum for one team.
