The most recognizable thing about Millennium Park is probably The Bean or, as it's officially called, Cloud Gate. After you take the obligatory selfie in front of this sculpture, stick around for some free entertainment. Take a tour of the Lurie Garden, walk through the open-air Boeing Galleries, enjoy an outdoor concert on the Great Lawn, or sign up to participate in a Chicago Greeters tour where a local teaches you about the history, architecture, and art in the park.
