BISTROT 20 / LE VINGT is a bistro near Notre-Dame that serves French dishes such as escargot, onion soup, and steak. Beef bourguignon and duck fillet are also available, and the onion soup is the signature dish. Staff wait without rushing diners who order in imperfect French, and a service item arrives after the meal. The raclette is on the salty side and must be ordered in a minimum of two portions.
