Personally, I think this exhibit is way more interesting than the Harry Potter: The Exhibition at Chicago's Museum of Science and Industry (right down the street from my alma mater, University of Chicago). It got a lot of criticism for promoting the movies, not actually being an educational exhibition. Most of the objects are authentic from the movie productions, but when there are cool books like the Science of Harry Potter: How Magic Really Works and Harry Potter and International Relations, it seems a shame to pass up an opportunity to do a really cool show AND still learning something.
I always try to explain that going to the University of Chicago is the closest thing you can get to going to Hogwarts without leaving the country.
This is the cafeteria.
