Squares on Riverside apparently has wireless access. I don't know if it costs or how much, but then it shouldn't be too difficult to proxy a connection and share it, so the likey £5/hour wouldn't be too expensive.
Also, looking again at the link posted yesterday to 'My Cloud' (hrmm, dreadful name) there is a place called Cafe Maximo Bar on Upper King Street which could be a pleasant place.[*]
But, as others have said, it all depends what we want from an eevening meeting. And, heresy tho' it may be to some, cost and quality of beer is not necessarily always the most crucial factor :-)
