Who's attending Ad:tech London this year on October 13-14 and is interested to meet up for drinks?

Ad tech London has really gone downhill in the last couple of years. I think the US one may still perhaps be worth attending, but the UK one is really underwhelming.
I concur - UK one is a disaster.
Dmexco Cologne (mid September) is a much better deal http://dmexco.de/2015/en/Index.html
