My other half and I are quite big on going to the cinema, and after looking in a London guide of unusual things to do, we came across the Everyman Cinema. We booked a suite for the two of us to see the Ides of March.
Booking is very easy to do online and worked out cheaper than going to your local odeon. The theatre itself is decorated quite lavishly in the waiting area, where you can order food and nibbles before hand. The main screen is huge with lots of comfy individual seats and sofas, with tables inbetween, and on the outside on the other side of the aisles are the 'suites' - two seater leather sofas which are very cosy. Table service is also available.
Although the cinema wasn't very busy when we went (it was a Friday afternoon) it was still an enjoyable experience, the staff are very good and considerate and go the extra mile to make your cinema experience an enjoyable one. I can imagine it would be better when the theatre is looking a little more full. It's very easy to get to as well. This is definitely a place that I will be returning to, and a little gem of London which few know about!
