If you are looking at the menu on this site, it's from 8/07. The one on allears is from 8/08 and has the salmon on the menu (one for both lunch and dinner) and this note:
Dinner Buffet Only Add-Ons
Braised Beef Roulades
Sauerbraten (Marinated Pot Roast)
Potato Dumplings with Bread Crumb Butter
Herring Salad Schleswig Holsteiner Style
Now, whether or not that particular dish will be on the menu when you walk through the doors, who knows. But they do have fish of some sort on there (I don't eat fish, I eat meat - we are opposites).
