I live in the Barbican, and know the area well, though unfortunately won't be there during the conference. I can recommend the Artillery Arms a few streets away (near Bunhill Fields) as place for an OSM pub meetup
one small suggestion for improvement - I was just checking out the mapbox map on
I think it would be user friendlier to get "Improve this map" in the local language (in this case German).
Thanks for the summary, very interesting. At last night's OSM anniversary meetup here in the UK we were just asking ourselves what had happened at SOTM-US
