A friend is coming into town and he wants to go out and have a good time. As I am unfamilar with Tokyo, I don't know exactly where to take him. At present, I am thinking of staying in the area close to his hotel, and have thought about the 300 yen bar (http://www.300bar.com/english/) and the Matsuzakaya beer garden (http://r.gnavi.co.jp/g008224/). Are there any other "must dos" in the area? I apologise if this is vague, but I don't know what's good in the area.
As this chap is likely to be in full-blown culture shock, it's probably best if we avoid places that are exaggeratedly Japanese in nature and orientation.
