it's not just a cinema where you can find movies to watch, but also it hosts a lot of international, local and regional festivals and competitions about cinema...so it's a good place to watch non commercial movies.
you can find in it movies that are coming and created by people who are not interested in cinema industry and making money out of it and who are only interested in creating something that really express what they see or want you to see, so you might find something real about egypt there.
just keep it in your mind if you're in cairo
