Looking for a UKLUG venue

Yes, I did just mention ILUG last week, and there will be more to come in the next few days. But in the meantime, Warren has a call for help out for the UKLUG in September this year. He is looking for a venue in London that can deal with 250 people for two days with breakout rooms etc. If you know of a venue, or indeed run a venue, then please contact Warren over at his site.
