My second time coming here! It's free on Thursday's and free after 5pm on Fridays and Saturdays. So you can spend as much time as you want or little time.
It is a bit smaller than the other museums in Phoenix. A lot of hipsters always taking pictures including myself hehehehe. Just kidding. But they have really cool contemporary art. The current exhibit they have now is the Ocean of Lights.
Warning: since it's free all day on Thursday's, the museum might be packed..
