Go big or go broke, amiright? The Plaza's 4800-sq-ft Grand Ballroom has hosted quite the history of fashionable soirees, from Truman Capote's legendary Black & White Ball to the marriage of Michael Douglas and Catherine Zeta-Jones. Bride Wars was filmed here, too. But taking vows in this mecca of stars and socialites can be costly -- $350 a head, with a minimum of 200 guests required to fill up the space. (We wouldn't dream of missing it, darling.) Price includes a three-course meal, open bar, designer cake, and a round of champagne. Eloise would be pleased.
