Thanks for the good ideas!!
We haven't set prices yet...and we are still fiddling with the menus.
We are planning on doing the little bags of cookies (like what your girlfriend would give you) and the rest more along the lines of standard Maid Cafe fare. Cute, fun, and nicely presented. Similar to the Chobits Bakery + Bakery from Kiki's Delivery Service. :3
Hehee, we thought about mochi, actually. I think it turned out to be too much a risk for a first time booth at the Con, or too expensive....I don't remember, I'll ask the rest of the crew.
Oh, and I really don't know if anybody else will be doing edibles....I hope so, it is a lot of fun to do!
