Located on the Left Bank near le Bon Marché department store, this busy wine bar was first established in the 1950's. The intimate, glass-enclosed space is furnished with an original zinc bar as well as ceramic tiles and vineyard-themed frescoes created by local artists. Seating is also available outside on a covered terrace. Au Sauvignon's wine selections range from an inexpensive Beaujolais to a pricey Puligny-Montrachet and hard-to-find bottles like Domaine Mardon Quincy, a little-known sauvignon blanc from the Loire Valley. In addition to wine, the restaurant is known for its tartines, open-faced sandwiches served on freshly baked Poilâne bread.
