We really enjoyed this tour! Connor, our guide, was knowledgeable and personable, and he did a great job projecting his voice to the group over the cacophony of downtown noises. I know some chicago history but most of the stories Connor told, I had never heard before. I always love walking around in the Loop anyway because the architecture is amazing, and then knowing the stories behind some of the buildings makes it so much better. The tour lasts about 1 1/2 hours and you get a little break in the middle at the Palmer House if you need to warm up, get a snack or use the bathroom - or just go in and marvel at the beauty of the place! I recommend this tour!
