If you are ever in Phoenix this is a must see museum. We only had two hours to look around and are planning to go back to see the rest of everything we missed. The self-guided tour is very easy to use you just walk up and it starts playing the story of whatever it is that you're looking at. There are some very famous guitars and other instrument's to see. We did not have time to stop in the cafeteria but the coffee smells really good.
