Welcome Mikee
Best fresh produce market I have ever visited was in Dinar, Brittany. Guy art the fish store asked what we wanted and we said that we were B&Bing nearby with no facilities to cook, he told us that was no problem, because if we bought the fish and took it to his mate’s restaurant, he would cook it for us. We duly did this and the guy in the restaurant charged us a small cover for cooking the fish and we ordered veg, desert and wine as normal – a great day.
You live in a great part of the world with brilliant coastal walks, plus the French maps, IGN, are really good.
