We stayed for dinner at this restaurant, it has it's own pier, so we could stay overnight with the boat. Very friendly staff and the food was excellent. I had "scholfilets", a nice fish and my wife a super Burger as main course, the starters were a beef carpacio and I had King Crab, both were very good.
They have also a restricted but well balanced wine list, they alo have a nice terrace and I presiume that in summer you better make reservations
I would certainly recommend this restaurant
