Chicago travel tips
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.
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.
