When I emigrated, people at work got me a ticket for this, almost didnt get let in as I had a City related shirt on and they didnt want football shirts in there...
I recall it was for a 2 hour period. I had loads of slices of pizza and maybe 7 / 8 bottles of beer. My Iceland Air flight was you had to pay for food and drink so was significantly full for the hours ahead. When I left the lounge I heard my name being called over the tannoy so a quick semi drunken sprint began to the gate. Was really weird leaving the lounge and re-entering the 'regular' waiting lounge areas, full of families and screaming babies and Scousers in replica shirts etc.... what a wonderful 2 hour escape it was.
