Nab a spot on the naughty or nice list at our 21-and-over holiday party.

Our holiday event is back for a second year, giving you the chance to visit Chicago's most beloved tradition with an adults-only twist. Sip on spiked hot chocolate and snack on candy cane marshmallows while exploring more than 50 trees and displays featuring new decorations for Christmas Around the World and Holidays of Light exhibits.

Take photos of handmade ornaments from cultures around the world. Snap selfies next to a 45-foot Christmas tree decked out with 30,000 twinkling lights. Dance to the beats of DJ Rae Chardonnay underneath our 45-foot-tall Grand Tree. They’re back! Santa Claus and Krampus return to ultimately decide if you’re naughty or nice.

Friday, November 16 from 7 to 11 p.m. (21+)
