The London LessWrong meetup takes place on the first Sunday of every other month. We're getting good at these now!  The next one is 2011-05-01 14:00, at the Shakespeares Head (official page) on Kingsway near Holborn Tube station.  Note that there's more than one pub in London with that name, so make sure you get the right one.  As always, we'll have a big picture of a paperclip on the table so you can find us; I look like this.  Hope to see lots of you there!
