Zurich ranks 1. Baghdad pulls up the rear.
I've only been to Zurich once, but I can vouch for it.
Modern building subtle and mature enough not to disrupt the urban fabric.
The perfect scale.
Cool airport too.
I haven't yet found the full list, but Dallas is nowhere to be found in the top fifty, which shouldn't come as a surprise given that Seattle and NYC are 49 and 50.
