All around great Chicago experience: the Cafe had a perfect Chicago dog and my spouse enjoyed his ham, green apple and Brie sandwich. The attendants were patient and helpful as I tried to pull up my Groupon; a free space to check coats, backpacks- all of which made the museum easy to enjoy. Thmany exhibits were fascinating, thought provoking, and interactive. We did a selfie with the Chicago skyline!. We spent 3 hours and if my stamina was better, I would have enjoyed another 3 hours. There is also a history walk outside that looked nice but was too cold. It was a great day!
