The groupon deal was a great value and easy to redeem. The Field Museum was excellent. The wildlife exhibits were phenomenal, and in my opinion, better than going to a zoo. There were many other amazing exhibits and I thoroughly enjoyed our stay. It was enjoyable for all of my children which range in ages from 4-17 years old. Highly recommend. My only complaint is that it closes at 4pm, and you could honestly go for two or three days and not run out of things to look at.
