Deep in the bowels of the Copley Square Hotel lies the city's first self-described "nitery" (though it's more of an upscale lounge than a "nighttime eatery"). Saint's designers obviously had fun filling this turn-of-the-20th-century space with various stylish and futuristic accoutrements: opaque-glass bathroom doors, plasma TVs and for a nightlife spot, the Back Bay's first bed (for lounging only). Black-clad servers and bouncers have been known to exude a bit of attitude.

Three distinct areas feature chic environs and expensive food and drink menus to keep the under-25 crowds at bay. Upon entering, patrons encounter the calm, blindingly white "Threshold Room," flanked by the "Living Room" (cavernous and usually crowded) and the more relaxed "Bordello Room" (romantically draped in crimson). Regardless of the locale, most tables are reserved for high-rollers; you'll likely be forced to stand with your selections from Chef Rene Michelena's eclectic "mini-cuisine" menu
