Chicago travel tips
1) Try the Chicago-style hot dog — you'll love it! | A Chicago hot dog is filled with beef sausage, hot peppers, other additives, and no ketchup. Try a real Chicago hot dog at HotGDog, Devil Dawgs, or Downtown Dogs. |
|---|---|
2) Bring warm clothes with you in Chicago, even if you are planning a summer trip | Cold winds are common in Chicago, often named “the Windy City.” Thus, a sweater and windbreaker will come in handy even in summer. The average temperature during the summer months in Chicago is about 25 degrees Celsius. In addition, summer is considered the high season in Chicago, which means more high-priced accommodation. |
3) Be impressed by the dimensions of one of the tallest skyscrapers in Chicago | The Willis Tower (formerly the Sears Tower) was once the tallest building in the world. It is now considered the third-tallest building in the USA and the 23rd tallest in the whole world. Plus, this skyscraper will look great in your photos! |
