Soufflen is a brasserie near the Eiffel Tower serving French dishes such as escargot, onion soup, and duck confit. The escargot comes with a basil and olive oil sauce for dipping bread, and the duck confit is served warm and tender with potatoes. A server who speaks Korean checks on the food during the meal, and outdoor terrace seating is available. The onion soup is on the salty side.
