Cocktails in Tokyo are def next level and a must if you're into that sorta thing. So many top bars.
Coffee I don't think is that great.. U will prob get better stuff in the states.
There will be too much great food to be had for sure - I don't even know where to start..
I don't know how many of the shops will allow photos - I suspect not many.
For clothes u should take a look at: CDG flagship, Dover street market, isetan men's, Visvim flagship, maybe yohji, maybe 1dk...
