Chicago travel tips
1) Walk around The Loop, one of the nicest neighbourhoods in Chicago
On a sunny, pleasant day, stroll through The Loop. This is the most atmospheric area, with distinctive architecture, wide avenues, and skyscrapers. Here you will see such attractions of the city as the Calder's Flamingo sculpture, the famous Chicago Theater sign, and the Willis Tower skyscraper.
2) Enjoy the finest paintings at the Art Institute of Chicago
If you love classical art, check out the Art Institute of Chicago. The entrance ticket costs $27. There you will see many famous paintings such as American Gothic by Grant Wood, Liz #3 [Early Colored Liz] by Andy Warhol, The Assumption of the Virgin by El Greco, and some paintings by Claud Monet and Pablo Picasso.
3) Drop by the Oriental Institute Museum in Chicago, which has nothing to do with "orient"
Despite its name, this museum is an excellent archaeological collection of various items from ancient Egypt. The museum appeared in 1919 and has collected a variety of artefacts, photographs, and even a 5-meter statue of King Tut. The entrance to the museum costs about $10.
