At only £9.80, with a further £2 off for seniors, it's less than half what some of the plusher cinemas are asking. And unlike the Barbican Cinema et al, it didn't sell out months ago - in fact tickets are still available online, and probably at the door too.
It may not have the poshest of exteriors, but once inside, the 'Delux Screen' has comfy armchair-like seats and great sightlines. Even a private sweetie kiosk to spend your savings in. If you don't mind a small-ish screen, highly recommended.
