"Welcome back." No truer words were ever spoken than on this week's episode of Top Chef: Las Vegas ("Culinary Olympics") in which the five remaining chefs faced their toughest challenge--a scaled down mini-version of the famed Bocuse d'Or--before getting cut down to the four chefs who would travel from Las Vegas to Napa for the season finale. To say that anything was possible is a gross understatement. It literally came down to the wire as the judges decided which of the five was the most relatively weak. To make it this far is no small feat in and of itself, especially given the caliber of chefs this season (overall, anyway) and it was clear that the judges had quite a lot of affection for each of the remaining competitors. Likewise, this week's installment was also a reminder of just how innately talented each of the remaining chefs is. I can't think of another season where all five remaining chefs were at the same level of skill as they are here.
