Reykjavik. The most beautiful place on earth (well, not the city itself, but the island.) The most interesting people, collectively, that I've ever encountered.

Last trip, we met a young woman who was a national-level sharpshooter, the lead singer in a punk band, and ran a business of some kind, I forget what. So many stories like that, random people just so alive and full of agency and curiosity. I agree with vibe being one of your criteria, that's the vibe I want.

Food is terrible, though, and more expensive than anywhere I've ever been. Staggering how expensive it was -- and I mean the prices in grocery stores, not swank restaurants. You'd have to be rich to eat well there.
