The venue will be Excel London. They have bars we can use, their site lists travel links and if there are others at the conference they would be close by. Date will be October 4th, maybe October 5th too.
And if you will be there, or are pretty sure, leave a comment so I know if to organise tshirts and if so how many.
(In response to an email, the cost is just getting there. And any drinks. Entry to the conference isn’t included or required. We’ll meet at a bar outside the conference but in the same building).
