I worked here for 6 months 11-12 years ago, shortly after it first opened. I've been there a hand full of times since then.
The theaters themselves are usually as presentable as I expect. Obviously the concessions are super inflated so I would recommend staying away from that if you can. When I was there it cost them 19 cents to make a bag of large popcorn that sold for over $4, to give you an idea of the kind of mark ups you can unfortunately expect from a big chain like this, or any movie theater for that matter.
The entertainment complex around it has built up nicely and there are a number of good places to eat/get drinks etc. that are literally steps from AMC
