With the improved quality of airport dining, having to pass a couple of hours between security and boarding is no longer a chore. The wide selection of restaurants at London Heathrow Airport reflects this improvement. Tuck into a hearty English breakfast before a long flight or just grab a quick coffee and pastry to go. Both choices are in plentiful supply at London Heathrow restaurants. For flights departing in the afternoon or late evening, you can even dip into some fine dining accompanied by fine wines before boarding your plane.
