Le Bistro du Grézac is so popular with the locals that I advise you to make reservations.

The inside is cozy but we opt to sit on the sidewalk where tables are lined up on both sides of the walk. A great place to people watch. There are traditional recipes and fois gras, pork cooked in lavender & honey. We both started with the huitres that were oysters from Bouzique.  My plat
was Moules a la Paisan, with lardons and creme fraiche. The wine was the local Picpoul de Pinet. J.s dish was another moules, called  a la facon. We will certainly return as well as to the Trois Salons.
