Great cinema - if you want to be in the huge auditorium, make sure it says the large screen when you book. VSOT means the film will be in its original language with French subtitles, VF means it will be (dubbed) in French. You don't book seats, so be there about half an hour early to queue and get yourself a good seat.
The screen is truly huge and made the film-watching experience fantastic, as did the lovely starry ceiling and feel of the place - although it's fairly basic decor other than that for seating/toilets/public spaces etc, rather than glamorously appointed. I am 5'6"/ 1.68cm and my knees were leaning against the seat in front - not bad, but anyone taller might want to choose their seats carefully.
You are not allowed to bring in food bought elsewhere - the very friendly staff will take your bag off you if you want to keep any food or drink. You can get it back at the end. You can buy popcorn/drinks in the cinema.
As ever, a few more ladies' toilets would make it a better experience.
