The Chicago History Museum offers a permanent exhibition Sensing Chicago where children can explore the city's history through their five senses. Kids love making themselves into a giant Chicago-style hotdog or smelling the (sometimes awful) smells associated with the city, or becoming part of a giant Chicago postcard. Families can explore the city's first 'L' Car and the first steam-powered locomotive to come through Chicago. The new Guild Gallery features a gigantic floor map featuring famous Chicago locations and an interactive experience about Chicago’s flag. There's a cafe in the Museum, as well as other nearby restaurants to grab a bite to eat. This summer, join the Museum’s 56th Annual Fourth of July Celebration with family-friendly festivities include patriotic music, crafts, a children’s costume parade, and the World’s Tallest Uncle Sam—all free.
