Langan’s Brasserie has been open since 1976 and has become something of a Mayfair institution; originally founded by Sir Michael Caine, Peter Langan and Michelin star Chef Richard Shepherd C.B.E, this eatery has changed very little since that time, although the menu is constantly evolving to encapsulate new cooking techniques and contemporary twists on traditional dishes. This is a wonderful place to get a taste of London and is just minutes from Green Park: this two-course meal for two includes a side dish, a glass of Champagne each and a coffee afterwards. Bon appétit!
