In the QuickFire Challenge, culinary superstar Daniel Boulud asks the chefs to re-create some of his favourite dishes…but the All-Stars are in for a very unexpected twist. The Elimination Challenge features a Top Chef first as the chefs are split into two teams to create the ultimate menu on-the-go for Retail Wars! Joining as guest judge is world-famous chef and retail food maven Lidia Bastianich.

In the QuickFire Challenge, the chefs fly blind and pick ingredients without knowing that they will be using them to make….ice cream! Later, in the Elimination Challenge, the All-Stars go deep underground to serve decadent late night eats to a crowd of 100 on the platform of Toronto's Lower Bay subway station. Guest Judge Chef Grant van Gameren is on hand to determine who's aboard and who will get left behind.
