Galerie Salon, 4 rue de Bourbon le Château, 75006 is a charming store in the 6th arrondissement filled with antiques, jewelry, candles and many ceramic pieces from the famed Astier de Villatte. I love the styling of the store where things are not perfectly arranged, but instead are perfectly unarranged. The only issue is that I can't seem to leave the store empty-handed. I suspect you will have same problem if you visit it as well.
P.S. The store is in the heart of the Saint-Germain-des-Prés area just off rue de Bucci. Head to rue de Bucci for some more shopping or head the other direction towards the Seine and check out the host of art galleries in the area.
