Dover Street Market
The New York location is one of only two U.S. outposts of Rei Kawakubo's Dover Street Market (the other is in Los Angeles, with additional stores in London, Paris, Tokyo, Singapore, and Beijing). It's basically a multilevel fashion emporium: each floor hosts miniboutiques from high-end labels including Prada, Marc Jacobs, Gucci, Alaïa, and Comme Des Garçons, alongside less well-known designers and street wear. The seven-story building is worth a look just for the people-watching. The in-house Rose Bakery is the perfect spot to refuel with a casual gourmet lunch or brunch.
