There is no more sumptuous Belle Époque dining room in all of Paris than the Restaurant of the Musée d'Orsay, overlooking the Seine and the Right Bank. The frescoed ceiling alone is worth the visit. You can imagine Marcel Proust and his friends sitting here (when it was the ballroom of the hotel adjoining the Orsay train station), gossiping of the rebels not yet known as the Impressionists, whose work now hangs in the museum. The recently renovated kitchen specializes in subtly simplified versions of traditional cuisine—grilled sea bream fillet or duck-and-peach supreme served with gratin dauphinois. The two-course prix fixe lunch is a bargain at only $20.
