It's cobblestone streets were once home to little more than dead cows. But things have mooooved on, and now this West Side neighborhood offers such eye-popping sights as the High Line, the Standard Hotel and the new Whitney Museum, as well as a host of upscale nightclubs and boutiques. Plus, you can still find a great side of beef at one of the area’s swanky steakhouses. And there’s even an Apple Store, in case your phone conks out.
