Built to celebrate the turn of the millennium (despite all that Y2K panic!), Chicago's Millennium Park hosts cultural events like concerts and exhibitions. Located in the Loop area, permanent attractions include Jay Pritzker Pavilion, the Crown Fountain, and the Lurie Garden. It's most famous public installation is probably the Anish Kapoor's shiny Cloud Gate (more commonly known as The Bean).
Unfortunately we currently do not have tickets for Millenium Park.
