I would love to see the figures for young people only. I'm 22, I spend £50 on a Wednesday or Thursday night and £70 on a Saturday nearly every week. It's about £12 for the return taxi, £5 entry and food (5 or 6 quid?). I usually go out with the same people, we buy rounds and bump into the same people and they drink smilar amounts so these figures are probably about average imho.
