It's not the best theater I've been to but it's very convenient. It's not stuck in a crowed mall where there is no parking, it's pretty much almost by itself.
With 16 theaters they have a pretty good selection, and the place is kept pretty clean. The only complaint is that they snack bar staff is ungodly slow, we were happy to have gotten to the theater 10min before the show started and sat down 5min into previews because we were waiting for the order.
All I have to say about Harkins though is that if you see a lot of movies it is totally worth it to buy the cup and the shirt, we never wear the shirt or even take it out of its package, but it still gets us cheap drinks and free popcorn!
