Things happen fast.
Okay, it may be strange, but this place is pretty freaking cool. Everything in here is decorated with psychedelic lights and glass and if you can handle some wall mounts that remind you of when Ed Hardy shirts were cool (oh wait--right, hahaha) then it's very much worth the trip.
Of course the best part of this place is the entertainment. A group of about eighteen women dance, play drums, ride motorcycles, play with giant robots, ride tanks, with a ton of costume changes throughout.
Highly recommend. At least once! If you do go, expect to pay Y4,000 which gets you the show, a small bento, and green tea. Don't expect a full bar. They offer canned beer and Chu-Hi and that's it. Do expect to have an awesome time! And there isn't a creepy vibe at all, it's really light-hearted and when I went, about a third of the audience were women. However, there is a girl's bar upstairs which is part of Robot Restaurant...it is men only.
