We may not officially be "The City That Never Sleeps," but Chicago is not exactly "Nap Town," either. The Windy City offers loads of late-night options. Last call at the best bars in Chicago is later than most cities, going until 4am or 5am. Considering we invented house music, you can bet there are some amazing dance clubs. You can go straight from boogying to brunch in Chicago. There are options for things to do around the clock. Or, if one 24-hour cycle is all you have in our town, we'll tell you how to see the best of Chicago in only one day.
