La Boîte aux Lettres is a French restaurant on the way down from Montmartre toward the Moulin Rouge, serving a starter, a main, and a dessert. The lunch course includes items such as carrot soup, a handmade burger, and tiramisu. Dinner service starts at 7 p.m., and main dishes take about 40 to 50 minutes after ordering. A waiter who speaks English well explains the French menu, and a steak ordered medium can come out tough or close to rare.
