Question for the floor.

[cadhla]

It looks like I will be having a book release party at the Ohio Valley Filk Festival. Yay! I've been asked what food I'm planning to have there, for the standard "are you bringing it in/are you giving us money and asking us to shop for you" lay-down, so I put it to you, the floor:

What should we be serving? My budget is limited, so please be sane, and stick to things like "tasty cake" and "candy corn."
