When I flew they had Lanson in the LHR Concorde room, obviously not the best champagne on the market but I was satisfied.

On board the guy in front asked for the '92 Dom Perignon (or was it '96) which wasn't on the flight that day. He got mixed up and asked for one that was on the Concorde Cellar list and not the Cattier Clos du Moulin that was on that flight. Luckily I noticed or I may have done the same!
