I've lived near Christown Mall for 30 years and the times have changed.  This is no doubt the worse wallyworld in all of Arizona, unless you want a good laugh.  It's like going to the zoo.  For shopping it's one star, for entertainment it's 5.  t's worth the 5 mins to go to the store on 35th ave and Bethany if you really need to go to wallyworld.
