Nightmare on Navy Pier Halloween Party

Get decked out in your best Halloween finery for this ritzy bash at Offshore Rooftop, where guests will be greeted with spooky "blood bag" welcome cocktails, a four-hour open bar and a haunting variety of passed bites (think prosciutto and mozzarella "eyeballs" and pumpkin soup shooters) while boogeying to music on the dance floor or participating in the party's costume contest. In between songs, make sure you glance at the bar's sweeping views of Lake Michigan and the city skyline.
