The elegant square circled by tall palm trees, in roughly the middle of the city’s downtown, is the hub for luxury shopping. Walk streets bounding the square to jot down everyone’s possible wish list of finds at Tiffany & Co., Louis Vuitton, Dior, and Bulgari (as well as major retailers such as Macy’s, Saks Fifth Avenue, Neiman Marcus and Nike). Slip into the sultry Clock Bar, in the Beaux Arts style Westin St. Francis, to clink martini glasses and compare notes. Anyone longing for a European vibe will feel right at home strolling the narrow, boutique-lined, almost-pedestrian-only Maiden Lane (car free from 11 am to 6 pm). Of course, shopping can sometimes be exhausting. Union Square makes it easy to recharge: the square has plenty of sunny benches for relaxing. Or one can order an espresso and a flaky pastry at upscale Emporio Rulli, with pleasant outdoor seating under market umbrellas right in the square.
