Ultimate Picture Palace
The Ultimate Picture Palace is a grade II listed building. It consists of an auditorium, a screen, and a tiny box office underneath the projection room. It certainly qualifies as minimalist, and has a varied programme of rep. films. A good place to see some old classics, even if they do tend to be on slightly scratched film.
It's been under new management since April 2011. The cinema now has a licence to sell alcohol (and presumably some snacks) so it's no longer necessary to stock up beforehand on Cowley Road.
