The Lock up is a fetish resturant in Japan that needs to be experienced. (Get a reso!). When you get there you are handcuffed and brought to a jail cell. All sorts of crazy things happen. The food is all mad scientist'y.
Odaiba is this crazy man-made island (out of condensed trash). There is a super cool amusement park, one of the worlds largest ferris wheels, a "future Toyota" car centre.. and an Edo style Onsen. Its a full day of wacky fun!
