@g1smd they have two offices in london at the mo. The Silicon Roundabout one opened Spring 2012. Sunday Times mag had a nice article at the time, but its a paywall job so see [telegraph.co.uk ] where its mentioned.
Oddly I often walk that Victoria station to coach station route and never noticed them ! ( being a cheapskate I get the coach home !)
