I saw good reviews on here for Untapped Tours and decided to try it. We booked it the first day we were in Milwaukee at 1:30 (the morning tour was full). It was a great way to get an overview of the city and learn some history, too. Mike, the guide, was very friendly and answered a lot of our questions. It was fun to go to different places and not have to worry about getting lost! We took some good pictures around town (the Bronze Fonz on the River Walk) and tried our first cheese curds when we got out at Clockshadow Cheese. We took a little tour a brewery (which gave free samples) and gave us a glass when we left. The bus only holds 11 so that is the maximum number on the tour which makes it more intimate.There is some walking involved but not too strenuous. I would highly recommend this especially if you want a good overview of the city.
