Spike Mendelsohn, the new spaghetti cat?Top Chef All-Stars premieres at 10 p.m. tonight on Bravo. This season features top contestants from the show’s previous seasons squaring off for a second chance at becoming a Top Chef. Luckily for D.C., we’ve got the culinary chops to have three hometown toques competing in the competition: Carla Hall, Mike Isabella and the darling of the DCist commentariat himself, Spike Mendelsohn. Hopefully, they’ve all had the time to look back and truly learn from the mistakes of previous seasons: have a dessert recipe in your back pocket, and don’t make scallops or a salad.
