Phantom of the Ambassador

Jump start Halloween weekend at the Ambassador Chicago's spooky evening soiree, where guests will be treated to a welcome glass of Champagne, themed cocktails, passed hors d'oeurvres, costume contests, live music (including a show from performers imitating the Sanderson Sisters of Hocus Pocus fame) and access to the hotel's 17th floor rooftop terrace. Plan a creative outfit, because the costume contest winner will get a free overnight stay and $100 food and beverage credit.
