Pleasantly surprised by the high caliber of this hidden gem in downtown Mesa! Ample parking in the structure behind the entrance and they even offer free admission on the first Saturday of the month. Each "room" had a different theme i.e. space, minerals, native American, medieval, etc. to make the experience even better. The displays were huge and life like with three different levels to explore and plenty of picture taking opportunities. There were two different bathrooms for guests, an elevator for use, and a small gift shop at the end. Overall, a great adventure for the day!
