Union Square and Chinatown

The city's finest department stores put on their best faces in Union Square, along with such exclusive emporiums as Tiffany & Co. and Prada, and such big-name franchises as Niketown, Apple Store, H&M, and Barney's. Visitors lay their heads at several dozen hotels within a three-block walk of the square, and the downtown theater district and many fine-arts galleries are nearby. By any measure, Union Square is shop-centric; if you're not that into shopping, you can find little beyond buildings of vague historical interest to entice you here.

A few blocks uphill is the abrupt beginning of dense and insular Chinatown—the oldest such community in the country. When the street signs have Chinese characters, produce stalls crowd pedestrians off the sidewalk, and folks scurry by with telltale pink plastic shopping bags, you'll know you're there. (The neighborhood huddles together in the 17 blocks and 41 alleys bordered roughly by Bush, Kearny, and Powell streets and Broadway.) Chinatown has been attracting the curious for more than 100 years, and no neighborhood in the city absorbs as many tourists without seeming to forfeit its character. Join the flow and step into another world. Good-luck banners of crimson and gold hang beside dragon-entwined lampposts and pagoda roofs, while honking cars chime in with shoppers bargaining loudly in Cantonese or Mandarin.
