Arsenal!
I was so lucky as to be invited to speak at the MarkLogic World event in London a couple of weeks ago and the event was hosted at the Emirates stadium, home of Arsenal London. Great location, especially since Arsenal is my favorite English team (even before BFG!). The timing couldn't have been better, Arsenal won the FA cup the weekend before and ended a long streak of years without a title. The stadium is a temple, and the hospitality areas are of course very posh, all in all a very good event in a nice area of London (with Otolenghi's just around the corner :-) ).
