Sentou Galerie knocked the Parisian world over the head with the huge success of its original, playful designs. Lamps by artists, avant-garde furniture, spiral staircases, rugs, and a variety of home accessories line this cool boutique. Look for the Spring Vase, old test tubes linked together to form different shapes, or the oblong suspended crystal vases that look great hanging above the dinner table or in front of a mirror. Be sure to stop by No. 18, a small shop devoted to the art of the table, with charming hand-painted plates, salt and pepper shakers, candleholders, and such. Métro: St-Paul.
