Both the shrimp pasta and the mango glazed tofu were pretty good but not outstanding, about the same quality as you'd expect at Chili's or Applebee's (as opposed to a really nice restaurant). The onion rings were very good and the milkshake was outstanding. Dessert was also very good, DH had the apple crumble and I had the cheesecake with caramel corn and M&Ms, which sounds weird but it really worked well together, I was very impressed with whoever thought that one up.
The movies are of the "used to be considered scary but now just ridiculous" type like Attack of the 50 Foot Woman, mostly they are the trailers from the movie and that's all. There are also ads for silly things and a cartoon, as someone said.
Our waitress was incredibly good, service was timed exactly right and she took some great pictures of us.
It was a really fun experience and we're glad we did it once, but I'm not sure we'd do it again. But we'd happily recommend it to anyone else, or go if we were with someone else who wanted to. (But it may also be that our meal was somewhat marred by the fact that DH's sister had had a life-threatening accident a couple days before and he spent most of the meal trying to get a hold of his parents, who live in the UK ... as does his sister, for that matter.)
