Chicago Architecture Foundation. I didn't realize it, but they actually have quite a large selection of different tours you can go on. I selected the Chicago Old and New: Intersections walking tour.
The docent for my group was Max, who was extremely knowledgeable and friendly. I really enjoyed her presentation style, and I learned so much about a few different types of architecture and some great Chicago history. It was an entertaining and educational way to spend a beautiful day, and I'd really like to do it again.
