Neiman Marcus

In a city square flanked on all sides by luxury retailers, the Neiman Marcus building is arguably the most impressive. Though the revolving doors feed shoppers directly into the bustle of the cosmetics department, first-timers often stop in their tracks to gape at the opulent rotunda. The structure is topped by an elaborate stained-glass dome, which was salvaged from the famed (and since demolished) department store City of Paris. As you ascend to the two levels above, floor-to-ceiling glass windows afford views of Union Square. Escalators to each floor reveal a central shopping corridor with the season's latest offerings, and designer shops line either side. (Offerings include Prada, Chanel, Gucci, Oscar de la Renta, Stella McCartney and many more.) Head all the way to the top for the home and kids section, where you'll find fine crystal, china and a colorful array of toys and clothes for tots.
