Brunch at the Auberge des 3 Hameaux in Choisel, just behind the Château de Breteuil, is undoubtedly one of the best brunches in the Yvelines, if not the whole of Ile-de-France. Affordable, all-you-can-eat, with good local produce and changing recipes, not to mention homemade pastries, we love it. Mind you, it only takes place one Sunday a month!
