A true bistro, Mon Plaisir in Covent Garden is one of the oldest French restaurants in London. Opened in the 1940s and run by the Lhermitte family since the 1970s, the restaurant has an unsurprising loyalty to French classics: snails cooked in garlic, French onion soup, tartare de bouef, leg of duck, and coq au vin all make appearances on the menu. The decor follows the same theme – the front room is 1940s-themed, there are traditional French artwork on the walls and the bar even came from a Lyonnais brothel. If you’re looking for an unequivocally French experience, Mon Plaisir is the place to go.
