One of Tokyo's newer glamour hotels is the Aman Tokyo. If you detect a pattern in the newer glamour hotel format in Japan it is the tower lobby, fantastic view, modern Japanese fit out etc
Not that I'm bored or anything...
In any case, if you find yourself at a loose end and don't want to take out a mortgage to have dinner you could try Aman for lunch some time. Here are some pics of their lunch set from a recent visit.
Octopus, new potato, black olive oil, glehnia (??) root
Milanese veal cutlet
