When you approach the entrance of Sleeping Beauty in Shibuya, you don't just walk through the door like it's the local convenience store. It doesn't open automatically like most doors these days. In fact, it's kept firmly locked.
There's an intercom outside. Push the button. When the door opens, if it opens, prepare to enter a different world.
Of course, the neighborhood where Sleeping Beauty is located isn't exactly Main St., USA. This is an area populated by love hotels, clubs and various and sundry other establishments catering to a decidedly adult clientele.
Sleeping Beauty is a "happening bar" and, as such, it fits in well here.
