Walking into the Money Museum feels a little like walking onto a game show set (or so I imagine). Hidden within the stately Federal Reserve Bank of Chicago, here you’ll see lots of flashy exhibits brimming with dollar signs, an interactive display that lets you design your own money, a game that detects which bills are counterfeit, and three different displays showing off $1 million (one is a giant cube of $1 bills, the others are smaller and made of $20 and $100 bills). Policy wonks will likely get the most out of the money museum, but it’s an informative (and free) stop if you’re in the area. Plus, there’s a brief movie about the Fed that doubles as a great resting spot on a hot or cold day. Expect to show your ID and plan on being scanned by security before entering. Allow a half hour.
