Usually go either here or the Aliante theater depending on where I am in town. Parking in the west lot is convenient so you don't have to go through the casino. I usually opt for a matinee since it's only $8.00 for an adult ticket. I believe they also offer senior and military discounts. The theaters and associated facilities have always been clean and well stocked.
My only complaint is the food selection; they only had microwave pretzels last time I got one but I usually stick with my go to movie snack raisinets ($4.00 a theater box) so this isn't a big deal.
