I've been kicking this idea around for a while now...you guys know the show Dinner: Impossible? Basically, a chef has a limited amount of time to prepare a gourmet dinner for special events with some theme to them. He's done for Pixar, Crayola, Sesame Street, a pirate convention, a magician gathering, a hot-air balloon gathering, etc. But never an anime convention.
The way I see it, the hook could be dishes to represent various genres, but I suppose that'd be up to the heads if this happened.
But I'd say it'd be worth a shot. How about you?
