> in Europe I would have given that award to London (limited experience, though).
I found London to be quite cosmopolitan. You can find every kind of food in great quantities there. For instance, I tried Ethiopian food there, which I never even heard of before. Didn't like it all that much, but there were several restaurants there.
> I'd almost guess that NYC, LA, Chicago, San Fran would beat Paris, too
I live in L.A., and I swear this city can not be beat for food. Even leaving out Mexican food, which could be argued is the native food food of L.A. nowadays, there are just tons of different communities here and lots of restaurants for each one.
> Best food I've ever had? Barcelona and thereabouts.
Never been there, it is certainly on my list though. I hear it is a party city.
