It's excellent. Just go.
We went there for a second time in about two years. The first time was impressive, the second was just as good. Some favourites were still in the menu (mussels), but the special (pickled herring) was surprising and delicious. Altogether, each 7 of the dishes we had, including the pudding, was a huge hit.
Service was first rate, too.
I can only recommend this restaurant in the strongest terms, and have nothing to complain about at all.
