Sentou Galerie knocked the Parisian world over the head with its fresh designs. 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. Be sure to stop by No. 18, a small shop devoted to table settings with charming hand-painted plates, salt and pepper shakers, candleholders, and such. Métro: St-Paul.
