It's getting down to the wire - this week the chefs will participate in one of the world's greatest underground dining events; A Dîner En Blanc. Each chef will create a picnic style meal with abundant ingredients to create an epic feast and pack it up for the first ever Dîner En Blanc picnic in Vegas.

In the penultimate episode, the Chefs will have to cook and create their dish while simultaneously instructing a mystery guest across the divider to make an identical dish. In the Elimination challenge, the Chefs will mentor aspiring culinary students and guide them through making a dish. The twist? The chefs will not be able to do any of the cooking.

It has all come down to this...for their last challenge, and the title of Top Chef Masters, the final two chefs will have 24-hours and the help of their most trusted staff from their own restaurants, to create a dish based on four letters - a love letter, an apology, a thank you, and a letter to themselves. They'll serve to a table of the culinary world's most esteemed critics.
