Alas, my experience wasn't positive. Scallops as hot starter was overcooked so they lost both texture and special its special sweet taste. Fish (kind of sole) was ok but nothing more. Dessert also was very average - though it was supposed to be a crep a-la Normand - it was an ordinary pancake with apples (wheat floor, not buckwheat as needed) in a calvados puddle. Sniff-sniff, I definitely expected more. And that was rather costly. Only thing I liked was local wine.
So you either take raw seafood like oysters - or you'd better choose another place.
Interior was fine though it's in a basement. Service was also nice.
