At this moment, i'm wringing my brain to try and think where we could meet up.. if we get enough of us together, I could always do something like phone up the Starbuck's in Covent Garden and suggest that we steal the whole of the basement-floor (obviously, we'd buy drinks- but it'd be an awesome place to meet up- sofas and tables galore)
If it's a nice enough day, we could meet outside (like St. James' park)..
Oo! We could get about 15 of us in one of the capsules of the London Eye! That'd be cool... although.. we'd have to check that no psychopaths are reading this before we enclose ourselves in a little bubble together for an hour!
