I think when they say "frozen meal", it's because they use Stouffer's mac and cheese (the restaurant is sponsored by Stouffer's). I'm not a fan personally, but my DH has been buying Stouffer's frozen mac and cheese ever since. He loved it!
That said, I thought all the other food was fresh and tasty. And as I recall, they did have at least 1 other kind of meat besides the turkey. But you really need to be in the mood for a Thanksgiving type of menu, since that's all they have at dinner. I thought before I went, no way will I be in the mood for that after being in the hot sun all day, but it surprisingly hit the spot. That said, the lunch menu intriuges me much more, and I won't book for dinner again unless they bring the characters back (unless DH has anything to say about it

).
