Tokyo -- it was cool, you could get up to an observation level in a lot of buildings, and there were often little shops at the lobby level. I was really low on cash, so I managed to buy lunch with my credit card at a Japanese Starbucks inside one. I might have been the first person ever to do that there: it took two workers and the manager to work the credit card machine. Fortunately they gave me my food first, because I was ravenous. Less fortunately, I'm not 100% convinced they didn't give up and just give me my food for free.
