Try Peak's Peppermint Kiss, German Choc Cake, and like the other recommendation of Fudge Brownie. Also, Genwax's Chocolate Orange is really nice too. Maybe a coffee mocha would be a good one too! I nixed a little cherry with a chocolate fo and called it choc covered cherries, that was popular. Good luck, lets us know how it goes. That would be a fun show, chocolate everywhere yummy!
