Discover the sights and flavors of Chicago on a 1.5- to 2-hour tour via the underground Pedway. The subterranean tour is the perfect way to explore the city without exposing yourself to the elements. Follow your guide to Macy's, the Thompson Center, City Hall, and more. Along the way, whet your appetite with Garrett Mix popcorn, artisan sandwiches, and frozen kefir. The 4pm tour on Friday also includes a wine tasting.
