If you want to see real lounges, visit any of the Virgin Atlantic Clubhouses, especially the one at London Heathrow (Library, Music & Film room, Miniature Golf, Free Salon and Haircuts, Free Full Bar and Full proper menu, not just snacks, games area, 360degree viewing conservatory).

Only problem is that you can only get in you are:-

a) Flying Upper Class
b) Are Flying Club Gold
c) UK AMEX Platinum or Centurion holder.

No one else, but then that the price to be paid for such a marvellous lounge.
