This is my go-to movie theater, mostly because it's very close to my neighborhood. I lean towards Harkins over AMC for unknown reasons. This Harkins is in Chandler Fashion, and parking IS bad, as others have mentioned. If you're there during peak times, choose a spot far away and prepare for a hike; fighting for a closer spot is quite the headache. Once inside, I've had only good experiences. The staff is friendly, the lines move quick, and I rarely step on spilled popcorn.
There are 20 screens, so there are always plenty of movie options. The really popular movies get several screens to allow for start times at frequent intervals.
One thing I appreciate about Harkins is the loyalty cup/shirt option. For $5, you can get a cup for the current year, and use it to receive $1.50 drink refills every time you bring it. That's a much better deal than $4-5 each time! Similarly, the $25 shirt will earn you a free medium popcorn per visit. If you go to the theater more than 5 times in a year, this is a good deal. *No, you don't have to wear the shirt each time... show it to customer service when you get your ticket and they'll give you your voucher*
