There are two different cafes inside the Musée d’Orsay. Café de l'Ours is the perfect place for a quick drink or snack, on a self-service basis. Café Campana is a brasserie-style café that serves up bigger meals.
You can also try walking ten minutes along rue de l'Université to the Saint-Germain quarter. Here, you'll find lots of lovely bars and restaurants, including the popular institution, La Palette, which is also listed as a Historic Monument. Order a wine and enjoy the very place that was once much-loved by Jim Morrison, Ernest Hemingway and Picasso.
