You've got some good taste! I really enjoyed Champloo, too. The manga of Revolutionary Girl Utena's pretty good, and Saiyuki is one of my favs. Although, I haven't been able to read any of Gunlock, since Tokyo Pop shut down :*( I'm not even sure if Minekure has finished the story yet XD Do you know if anything beyond Reload has been translated into English?

It's an interesting idea. You might want to start a poll or solicit college campuses, or find a way to gage interest in something like that. I think it'd be fun, but there's a lot to know about food inspections, employment, and advertising. It's a cool idea. I think it might be good to find out if a specialized restaurant like that would get enough people. Maybe it could be something to attract tourists? Schaumberg's not too far from Chicago. I can't remember if the Metra goes out there or not. It's a really cool concept! Sandwiches and books/manga work well together :3
