Plan a whole day - so much to see for all different interest and age levels.
For parents, you may feel rushed to see it all by your small kids fixated on the dinosaurs or animals - I had fun going as a parent bc my 3 year old had so much fun. If going with children, plan ahead and manage your own expectations - you won't get to see it all if you are with young kids.
I've been before with out kids and could stay all day. I really enjoyed the Native American exhibit - so well done and thorough.
The exhibits are so diverse and well done that even a non museum lover would find at least something interesting and engaging.
This place blows The Shedd away - no comparison.
Cafe up front has good sandwiches for lunch and there is a McDonald's in the basement.
One of the city bus routes will drop you off right in front or take a taxi.
If I'm ever back in Chicago, I'd go again.
