As a small venue for music, poetry etc. there's the (fairly dark and intimate) space in the cafe downstairs. Here you can get, um, a variety of teas and some coffees and juice and bits of food which are generally suitable for non-meat eaters - all served by volunteers.
Upstairs has a large space which is used for the slightly rowdier events.
There's an unexpected piano at the bottom of the stairs which is sometimes the source of some entertainment, although it's not always entertaining for the anticipated reasons.
There's even a small dedicated art gallery in the front, which often features people sitting around either working or socialising.
As long as you avoid the occasional puddle the front of the cafe has a number of sockets, and I've never had any difficulty getting to an empty one.
The place also has free wifi, but as it's being shared by at least a dozen hippies at any one time (and it has one of those maddening preachy pop-ups when you first log on - asking you to be considerate and not hog the bandwidth - which replaces all 30 tabs you had open and at least some of which you never manage to retrieve) it's not terribly reliable.
The seating varies hugely; I've been in armchairs, on benches, in upright chairs and even perched on the floor at times.
The hot drinks are... not amazing.
If you're wanting to do some work or have a nice relaxing time I wouldn't recommend it. If you're looking for a 'wacky' community-led venue for arts and music then this is the place for you. Just don't leave your valuables unattended (as the staff keep telling me)!
And while I appear to be firmly dissing the place, this is just my dislike of using it for work. It's great for lots of things and needs saving from the threat of closure...
