I've been there a number of times, and it's fairly clean, with pretty good service, which is why I keep going back. The on-site child care even seems to keep the noisy kid level to a real low. The factor that keeps me from going more often is that they're cheap in the climate control department.
There can be five people in a ten PM screening, but still hot, so you know it's not because their A/C unit is working hard.
Star Trek was a great movie, but I'd have enjoyed it more without two hours of sweating and thinking about how much sweat other people have been depositing into that seat before me.
