1. I know no one visits a city to watch movies but Phoenix has a drive-in theatre (West Wind Drive-In in Glendale) which does double-features. That’s a novelty nowadays.
2. There is also a retro-themed dollar theatre (OK, $1.5 on Tuesdays, $3 on other days at 2015 rates) near Bell Rd and I-17 (called Super Saver Cinemas) which has the manager coming in before some movies, reading out the movies going out/coming in and cracking fun at himself. There are even arcade games there.
3. For food, in case you are feeling adventurous check out a vegan restaurant named Loving Hut near 35th Ave and W Union Hills Dr.
4. Lastly, the Desert Botanical Garden will make you appreciate cacti in a way no other place can.
