Most are free. There are 3 main restaurants that have the same menu. We never had any problem getting in.
Cagneys is the steak house. It is a minimum of $20 extra per person and $45 for "the special part of the menu".
Le Bistro is extra. I think it's $12 extra, french food.
The sushi bar is $10 extra. And I think the Asian rest is extra but not sure how much.
There is the Salsa, mexican, that's free but you will need reservations.
