Top Chef Masters is back with a brand new host, new judge and a new format - so why not start the competition off with something familiar, the most notorious of all Top Chef challenges, Restaurant Wars.These master chefs have opened their share of award-winning restaurants, but nothing could have prepared them for the pressure that's on now. With their egos on the line, the knives come out right out of the gate.

In this week's quickfire challenge the chefs must use each of their five senses to identify mystery ingredients - however they can only use one of their senses at time. In the elimination challenge, the masters help a man propose to his unsuspecting girlfriend on her favorite show, "Top Chef Masters." In a six-course meal, the chefs must create dishes that reflect different stages of the couple's relationship, but could one bad dish ruin the whole plan?

Crickets, nightcrawlers and beetles, oh my! These master chefs are used to cooking with the finest ingredients but in this week's quickfire they're forced to make a delicious dish out of some horrifying creatures. The elimination challenge however, makes it all worthwhile when the chefs compete to sell their dishes for $100 a plate at a charity fundraiser. For every plate they sell, the money they receive goes directly to their charity of choice and these chefs are in it to win it.

The masters are in for a treat this week when two high-profile celebrities visit the top chef kitchen. Pop Star and trained chef, Kelis, drops by to judge a very meaty quickfire challenge and then "Mad Men" actress, Christina Hendricks and her husband, actor Geoffry Arend, enlist the help of the cheftestants in a special 60s themed elimination challenge.

With today's technology, everyone wants things to be done as fast as possible. In this week's quickfire, the masters will have 15 minutes to create a breakfast from start to finish- but they can only use one specific tool from the modern day kitchen. For the elimination challenge, the masters must trade in their aprons for goggles and stovetops for Bunsen burners. Using traditional high school chemistry at a Science Fair, the master chefs must create their most palatable creations.
