I recently held a work presentation at the RAF Club in one of the entertaining rooms (Presidents) for shareholders (now that I am a civvie...).
The event ran like clockwork, the staff were superb and all in it was half the price of doing a similar event anywhere in Mayfair. My guests all commentated on how special it was to be invited into such a special club.
It is a brilliant club and by far and away the best value for money in Mayfair - sure you can get a cheaper room if you go to the travel-lodge in Acton, but thats not the point really is it!
Long may it stay as it is, and hopefully those moaning on here about it being SOOO expensive (really??! I am also member of somewhere close by and I can assure you that the annual subscription is 3 x what the RAF club is, plus a punchy joining fee) won't come and dampen the happy vibe the RAF club has.
