Hi all

Probably a basic question, but I can't find an answer. I'm flying to Dubai from LHR on Friday of this week, returning early on Monday morning at 02:25. Both flights in Club World. The BA website tells me that this is a sleeper service, but having never flown on one before, I don't really know what this means. From googling, it seems as though you're expected to eat in the lounge prior to flight, as the on-board catering is limited. If this is the case, does it mean that there's proper dining options in the BA lounge? And that there's no food service on the flight (other than the Club kitchen?).

Any info would be appreciated- thanks.
