I think they do OK... really making their money off the food and drinks.
They have a good sized menu of decent food with full bar and good beer selection. Easy to drop an extra $40+ in two hours.
Pretty much give away their monthly pass thing for $30 for unlimited movies (one free per day) since they know you'll buy more stuff.
They did 1989 this month so played Back to the Future 2, Batman 89, Bride of Re-animator, UHF, Pet Sematary, The Burbs etc.
