If you have the opportunity to visit St Louis, I highly recommend the art museum. I did not have enough time to tour the entire museum due to time constraints, I know that I could easily spend hours there. There are 3 levels with a new expansion coming in June 2013. I asked someone there and they said this add-on huge and would allow them to show even more artifacts that they have stored in the back. It it's current state the museum is 3 stories. I barely had enough time to finish the 1st level before I had to leave. They have a gift shop, several restrooms, snack bar, and many docents ready to answer questions. I look forward to continuing my visit next time!
