London's East End. Shoreditch, Hoxton, Redchurch, Brick Lane, and Arnold Circus are just a few spots where you'll find some of the world's coolest people. What really strikes me is how beautifully diverse it is (and, yes, suits and facial hair are still in). Somewhere in one of these oversized lofts, there must be a guy in vintage black, petting a monkey while doing the "sprockets" dance.
Here are big lofts, big galleries, and the most pleasant little park at Hoxton Square where the locals sit and enjoy reading real paper books. Head east a little bit, and it's more like a real neighborhood: expensive vintage and the perfect roundabout.
Walk a bit south, and it gets more high fashion. A great spot to grab some organic tea and people watch!
