If your idea of good food is fish & chips or hamburger & salad, please go elsewhere or you will be disappointed.
I have been there with my wife last August, as I always do if I happen to be within 100 km from this place (unfortunately only once a year or even less).
Although we arrived for dinner without reservation (an hazard in peak season) we were given a very nice accomodation (in fact all the place is in a good location, in a pedestrian area and next to the piers of the "port de plaisance").
The strong point of this place is oysters & "coquillages", so my wife had some of them (excellent, but I do not like them) and then we both had other fish plates, all very good.
There was personnel in good number, kind and efficient as suitable for a place of this standing, and waiting time was reasonable (in 5 minutes you can just take something from the fridge and pun it in the microwave).
This place is not cheap; newertheless we feel it is worth its price (we are well aware that good fresh fish has a price, especially in high season) and will return again at the next opportunity.
