In the high stakes Quickfire Challenge, Chef McEwan asks the remaining chefs to create their take on a classic lunchtime combo. Later, it is time for the classic Top Chef challenge – Restaurant Wars! Divided into two teams, each group must create – and execute – a brand new restaurant concept in 24 hours. The home base for this challenge is the flagship operation of internationally acclaimed chef and restaurateur, Susur Lee, who also acts as a guest judge.
