Quickfire challenge: After a road trip to the Stanley Hotel, the chefs were asked to create a dessert based on their worst nightmare. Padma was the sole judge.
Elimination challenge: Since this is Top Chef's last week in Denver, the chefs were asked to make a dish that illustrated their journey on the show so far. The challenge took place at the governor's mansion with guests including the governor himself, his wife, and esteemed chefs from Colorado.
Since this is the last LCK (for real this time), this was a special two part episode.
First challenge: Bruce, Joe, and Brother had to make a porridge dish.
Second challenge: Joe, and Brother could make any dish they want. The winner will be voted on by Colicchio, a guest chef, and the eliminated chefs.
We will know who won and who lost on next week's Top Chef.
