I have seen youtube videos saying that you can ask for custom dinners in the Yacht Club restaurant. My wife is not a salmon fan but would enjoy swordfish or (even better) Chilean sea bass. I know these fish are available on the ship. If we put in a request in advance either in the restaurant or with our butler, would they be willing to cook that for her instead of the salmon? Sorry if this is just a nube question.
