Plan your visit! This world-class art museum is huge! With so many galleries, you could spend days here, so it's best to prioritize what to see. On our recent visit, we saw the Andy Warhol special exhibition before visiting the American Art, emphasis on Georgia O'Keeffe (12 works on display in a single gallery!) followed by the Impressionism galleries (this museum has one of the best Impressionism collections in the country!). That took up the bulk of our 6 hours at the museum! On our last visit, we saw the Chagall windows and the reconstructed Chicago Stock Exchange Trading Room as well as their architecture and sculpture courts. Who knows what we will focus on when we next visit! Be sure to take a map so that you know where you are going within the building. Also, re-entry to the building is allowed so you can go out for lunch or a take a break outdoors.
