No theme/structure - just come along and chat about whatever you want with others who are trying to do the most good they can in a rational, evidence-based way :-)
We'll be in St James's Park, weather-permitting. Let's meet just west of the cafe (www.royalparks.org.uk/parks/st-jamess-park/food-and-drink/st-jamess-park-cafe). If the weather's horrible, we'll descend on the Lord Moon of the Mall instead (a 5-minute walk away), or if that's too crowded, one of the other pubs on that road.
Turn up any time before 9:30pm or probably later - one of the organisers will stay til at least then, but we expect some people will stick around until at least 11pm as per usual.
Call +44 (0) 7910 094 247 if you have any problems finding us.
