Armed with ex-Le Gavroche head chef Thierry Laborde, Peyton has created an elegant, off-the-beaten-track brasserie serving wonderfully cooked portions of fine French food from the confines of the Wallace Collection's sculpture garden. Share a poulet bio "Wallace" - a whole organic roasted black leg chicken served with green beans and thin, salty pommes allumette (£60); half a dozen Tsarskaya oysters (£11.50); or roast monkfish with broad beans and wild rice (£18.50). If you're looking to combine cultural and culinary delights, The Laughing Cavalier (1624), by Dutch painter Frans Hals, resides here, as well as a delectable collection of 18th century French art and furniture.
