SteveD and I are working on a meet-up at the Ace -
My plan includes being as relaxed as possible, NOT wearing loud clothing, NOT blocking sidewalks while reading incoprehensible London maps, NOT taking every possible ubiquitous photograph, NOT talking about politics, NOT eating hamburgers, and NOT ruining ALL of your birds... 
You'll have to watch some newer English movies CBJ, but here is some "Int" that I've picked up via the BBC:
a. Brit's are far from relaxed, (just make a loud noise on a train and watch 'em jump!) but if you need some help tell them that you're Canadian and they won't screw you over, (completely)
b. ALL maps are incomprehensible,
c. Britain is such a melting pot of cultures now that one more person wearing loud clothing shouldn't stand out, unless that clothing makes a LOUD noise!
d. There's a MacDonalds on every other block,
e. No-one has referred to girls as "Birds" since the Beatles split up, (but if you mean you don't intend to ruin some pigeons in Trafalgar Square, that's a good idea, do your bird maiming at home where it's ok)
f. If you take any pictures of anything that resembles a public building or monument the cops will probably arrest you as a suspected terrorist, and
g. For God's sake don't wear a coat in the subway (tube) on a warm day or they shoot you in the head 12 times as a suspected terrorist!
Cheers, Terry.
