You are in London, so the polite thing to do is to go to a pub! The Cross Keys, located in the deliciously glamorous Chelsea neighborhood, is somewhat traditional and historical, but has been recently modernized with up to date amenities yet kept its old-style flair. The Cross Keys has developed quite a good menu of well-executed dishes served in its typical pub atmosphere. The menu changes regularly, but if available we highly recommend the truffle brie cheese starter. You also cannot go wrong with the typically English Sunday Pub Lunch, a meal consisting of roast beef, vegetables, potatoes and Yorkshire pudding, or even just try a pint of lager or ale. A lovely very British experience!
