We had to cancel Claude Bosi (and lose our deposit) because of flight problems. We managed to book the Ledbury for next week. They still have a vegetarian menu.
AA delayed our 10:40 flight to 19:00, which would have meant arriving in London at 7:00 the morning of the meal rather than the night before, so we re-scheduled the flight. A lovely meal after little sleep didn't seem a good idea.
