Title says it.
We opted for the trout and sole dishes. Fish was very fresh (but did not expect otherwise) and well cooked.
However, service was very indifferent, hardly any greeting or otherwise any interaction between staff and guests. Got the feeling we were just being tolerated. Would have been maybe less surprising at the end of the season, but our visit was just before the start of it.
Also, charged 9 euro for a bottle of still water, a price more suitable for Brussels than the Ardennes.
