I've seen this idea proposed in the past, but there has never been one established at Zenkaikon!
Lots of other conventions; Otakon, Fanime, Anime Expo... have maid cafes and I think it would be fun to experience and see one here.
I think it'd be a super cute way to interact with other con-goers and would encourage people who are normally shy to step outside of their shell.
Thoughts?
