I've been sort of binging this over the past couple of weeks. I'm in the middle of season 11 right now. (It's nice background TV). Despite being an Iron Chef, and owning several successful restaurants, I think Bobby is often underrated so I think it's fun watching him cook outside of the Southwest flavors, when called for. I've seen a huge range in quality/skills of competitors, which I can understand in the beginning when the show is new and no one knew what it was, but as we go it seems more glaring.
I actually like her*, but I am getting tired of Katie Lee for some reason. I don't even think she's been on the most, among the various "friends". It's not horrible or anything, I'm just tired of seeing her. (*yes, I even liked her as the "Katie LeeBot" host of the first season of Top Chef).
