I've never been to one, I'm not aware of them ever being in the UK, so growing up it wasn't an option. There is one here in Adelaide but it's over the other side of the city and way too far for me to travel just to see a movie. There was one very close to where I live but it closed down before we came to live here, there's a push on at the moment to get it open again but funding's an issue as always. I think I might go for the novelty if it did reopen but couldn't see myself making a habit of it.
