Good? Yes.
Worth it? Arguably.
A true tasting menu experience? No.
Unlike most tasting menus at an in-land restaurant, the chef who designed the menu is *not* the one preparing it. For obvious reasons, he or she cannot be on every ship, and I believe is not on any ships. The food is still good. The preparation is still good. But, there's something that the meal lacks when the chef preparing the meal isn't the one who designed the meal. My wife and I did it once, and while we don't regret it, we won't do it again. We've done a few tasting menus, and it was on par with all of them - but not better than them.
