Been there twice, once on each of our last trips, and to be honest, we eat there more out of convenience (we stayed at Beach Club, then Yacht Club), and while it is okay, I would not hurry to return.
The clams, the star of the show, so to speak, end up getting knocked around by the spoons so much that half of what you grab are empty while the clams fall to the bottom of the pan where you don't know if they are good or not. The mussels fare better and taste fine. There were no crab legs to be found despite the ads on the elevators in the hotel (LAWSUIT, just kidding). There might have been one or two other fish dishes, but nothing stands out now.
To be honest, and this sounds blasphemous, but they have too many desserts (one side of the 'square' plus a whole other area near the hostess) and not enough of the substantial foods, so to speak.
I'd say skip it and hit up Biergarten or grab some fish and chips in England.
