A pair of special guest stars stopped by Top Chef Season 12 Episode 4.
First, for the Quickfire Challenge, the contestants frequented Cheers, the bar where everyone knows your name. They had to come up with some bar snacks there that impressed none other than George Wendt, the actor behind Norm on that iconic sitcom.
Elsewhere, Emmy Rossum joined the judges - and she threw a curveball at the aspiring stars.
They had to make last minute adjustments in order to accommodate the gluten-free diet of this Shameless beauty.
Also, Top Chef Masters alum Michael Schlow made an important appearance.
