Well, the counter service restaurants have very limited food. Basically your burger, chicken fingers & in a few place a pastrami sandwich. We've had the burger & chicken fingers and they are only okay. They microwave them so the bun on the burger is kind of gross.
As for the table service restaurants, there is also very limited choices. Here is what is available:
chicken soup w/ matzo ball
vegetable soup
brisket
honey glazed chicken breast
ginger salmon
cheese lasagna
kids meals: chicken fingers, hot dog, macaroni & cheese
apple strudel
chocolate cake
pareve cheesecake
breakfast: cheese omelet or cheese blintzes
There are ice creams and some packaged stuff that are kosher.
We honestly go there for atmosphere and not food. Think airline meals and you won't be disappointed.
If you are staying onsite sometimes the chefs at the resorts will go out of their way for you. When I stayed at POFQ the chef there was very accommodating.
