Chez Plumeau is a restaurant in Paris that serves French food along with coffee and wine. It sits near the Sacré-Cœur Basilica, behind Place du Tertre in Montmartre. The menu includes French onion soup, escargot, croque monsieur, and steamed mussels. The terrace is shaded by flowers and leaves during the day, set back from the crowds on the square, and the steak is on the tough side.
