This is a highly recommended way of getting round Chicago and finding out lots and lots and LOTS of very interesting information. There are plenty of places to hop on and off the buses, which are very frequent. The tour guides are amazingly knowledgeable. Each one of them adds more and more interesting information about the city, its history, its art and its architecture. Many thanks to Bongi and James, who were the two guides we spent most time listening to. Both full of facts and very entertaining!
