Booked champagne afternoon tea as part of a birthday long weekend visit to London for my wife and the experience really lived up to expectations and more. A great balance of quality and professionalism in luxuriously comfortable surroundings without any hint of pompousness from any of the management or staff. Once you have booked your table it is yours for a minimum of an hour and three quarters so no pressure to leave and a seemingly endless supply of finger sandwiches, cakes, scones etc. means you can eat as much as you like during that time. Expensive but certainly worth doing as a special treat.
