I remember back when the 747 was a new plane. The first one I ever flew on was on an Air France flight from Paris to the US. I flew First Class and the upstairs was a cocktail lounge for the First Class passengers. After takeoff they took us up there, mixed our first drink and then left regular size bottles of whatever you were drinking sitting at the bar and you could make your own drinks. When dinner was served they came up and got you and you went back to your regular seat for dinner.
