Sel De Mer translates to "salt of the sea", so you guessed it, it is a seafood restaurant. And yes, a French one. The Holland America folks call it "French seafood in a traditional brasserie setting."
It is quite different than other speciality restaurants on Holland America. There is not a base price for a meal at Sel De Mer. It is a la carte so if you're not careful things can really add up, especially if you want starters like their seafood platter!
As you'll see in this brief review, they deliver a few touches along the way that make the dining experience memorable, including showing you your fish before it turns into just the insides. Happily the fish is not still alive when they show it the first time. It was pre-dead.
