Isaac Mizrahi was on hand to guest judge on 'Top Chef All-Stars' (Wed., 10PM ET on BRAVO). Since his forté is fashion (as opposed to food), his job was to critique how the dishes looked -- they wouldn't be tasted (?!).

Each chef created something from a personal inspiration. Richard wisely catered to the designer's penchant for basic black, making black chocolate ice cream with liquid nitrogen, which Mizrahi deemed "so sophisticated."

Antonia's favorite book, 'The Giving Tree,' turned out to be Mizrahi's favorite, too! Still, he wasn't a big fan of her foodie rendition.

Angelo's saying he was inspired by fashion designer Roberto Cavalli didn't do him any favors with the judge, nor did Mizrahi like that the cheftestant had scrawled on the table under the dish "like Charles Manson." Did he notice Angelo had written "crocadile"?
