You could live your whole life just eating moules frites they taste so good out here. Of course as ever it’s the simplest cafe by the beach where you get the best tasting seafood. Uncomplicated, (relatively) cheap, fresh and served without any bullshit. This place Le Petit Saint Michel was where we kept coming back to. Also of course has all the other local specialities, crepes, galettes and so on. The beach is good nearby too, smooth white sand and shallow water until you have walked out a bit, which is good for children. The best time to come is at the end of the day when the sun has lost its fierceness and the French are starting to go home. Then you have the place almost to yourself. There is a ruined chapel which you can walk out to at low tide. It’s a sort of miniature Mont Saint Michel, hence the name.
Of course, not forgetting the oysters!
