One of our favorite places in downtown Mesa- (also owned by our friends!) a great family friendly place to grab a Cider, or a pizza (Myke's Pizza) and the best coffee (PairCupworks) in DT Mesa. We like Art Nights here and Monday night Bingo. You can get pizza or carry in food from any other downtown eatery.
One of our favorite dates was here- we love this place- with exhibits and demos of music and instruments from every country and genre- this checks all the boxes for us. Tickets are 20/adults 15/teens 10/kids and this is 30-40 minutes from downtown Mesa.
If you're Jonesing for a hike do this one early in the morning (September is still really hot!) and bring plenty of water. This hike is fairly shaded for the first section around the lake and a fun way to see water and saguaro cactus, plus you can turn around at any point. (It is fairly rocky)
