A good slightly left field venue for a show I'm trying to put together in London, I've thought of all the obvious choices, but want to see if there's any secret hide aways that would be good.

Capacity: 100-150 max
Central/North/East London and easy to get to would be a plus.
if the venue had some kind of ceiling projector and screen that would be awesome.

Does anyone know of anywhere? was considering emailing a promotions company and working with them on putting it on, but would rather do it independently if possible

Please and Thankyou :)
