Yes we have one, they are really lovely, but expensive as cinemas go, but a great addition to the town, ours is fairly new. I've been visiting Everymans for a good few years, there was one close by to our previous town. I have never heard of the subscription you refer to Nan Kate, my experience is you merely pay for your tickets when you go. I would add that the last film we saw was "Elvis" and that was back last year, sometime I think in the summer, so haven't been recently. As Louisa states you just book tickets on line, or if you happen to be passing you can pick them up at the box office and avoid the booking fee.
I would add that the sofas that accommodate two people, if there is only one person on that sofa then the full price for two applies. I only mention that because I took both my grandchildren to see a film last year, there wasn't a lot of choice trying to get one single seat next to the sofa as singles are few and far between. Something to bear in mind if you book for an odd number of people rather than an even number.
Aside from that all lovely, they serve food and drinks and the servers come round inside prior to the film starting to take orders. Ours has an upstairs outside terrace and the decor is very retro sixties, pictures of stars like Bardot from that era adorn the walls.
Hope you enjoy the experience when yours opens.
