The 'good date ideas' thread

Whilst in the City go to Postman's Park, a little memorial garden with handmade plaques commemorating people who died saving other people's lives, with loads of lovely little handmade plaques...makes a change from a brass plate on a bench: http://en.wikipedia.org/wiki/Postman's_Park
watch the public and gossip about them, like they're gossiping about you, although you pretend not to notice
Clissold Cemetary, which is really pretty imo, but the date ambience is usually ruined by all the ugly dudes fucking in there.
... as is breaking into your local park after dark with a picnic blanket, a bottle of red, no glasses and an empty stomach.
Meet in a pub, get wankered on real ale, have a massive argument about something or other, fuck in the toilets.
Its summer time. Late night getalo at Gelupo always seals the deal
go to tate modern, make fun of all the "art", drinks on the riverside, moonlit stroll to follow.
fish and chips and six for a fiver (and jumped fence into a park)

I've done all of these dates already... More suggestions please. I need a good one for next saturday.
