A South Loop playground in the Dearborn Park area, donated to the Chicago Park District in 1990.

An aquarium built around a touch pool where small hands are actually welcome, plus a dolphin show big enough to hold a kid's attention for a whole hour.

A major art museum on Michigan Avenue with a dedicated family learning center, free stroller loans, and free admission for children under 14.
