Au Sauvignon is a traditional Parisian bistro near Le Bon Marché in Saint-Germain that serves cheese, charcuterie, tartines and wine. The menu includes a daily special, house-made terrines, salmon dishes and croque-monsieur, along with homemade desserts. One family has run it for 70 years, old posters hang on the walls, and blankets are provided on the winter terrace. Indoor seating is tightly spaced and somewhat cramped.
