I like this theater quite a bit. Since it's not a giant megaplex, it's usually less crowded and chaotic, but it will almost always have what you want to see, even if it's only 20 screens.
The concessions are theater prices (so pretty expensive), but come on, would you expect anything less? Luckily their popcorn is good and they offer a different number of drink/popcorn/food combos.
The staff has always been friendly too, I've had no problems there. They're always ready to greet and help you out.
Overall, I think AMC Westgate 20 is a great place. Check this place out the next time you want to see a movie, you won't regret it.
