OP, are you the guy who opened this restaurant? http://www.chouanime.com/

Because if so, I have two questions for you.

1. Couldn't you find cuter girls to work at this place? I thought that's the whole point of a maid cafe.
2. Detroit?

Anyway, I'm a 27 year old male living in the South, and I wouldn't go to a maid cafe unless I'd been dragged there by friends. I'd feel creepy as hell otherwise, especially if the girls working there were young. I really don't think this idea is viable in the US anyway; tastes here tend more towards "tits and beer" than "cute girls and tea".
