This museum is awesome! I made it a point to go there while visiting from California and am so glad I did. It includes two museums, Art History and Natural History. If you go after 3:00PM, tickets are half price :D There is a great collection of art and I loved the jewels and rocks exhibit on the natural history side.
The only thing I would like to see here is some special exhibits of famous artifacts. Maybe they do them throughout the year, but when I was there, there was nothing iconic or prestigious for me to recognize. But other than that, the collection they have is very complete and interesting.
