Club space ? Was wondering if they allow 18?

you can see at the bottom it says 21+, obviously it’s telling me the answer. But, I have heard from friends that they allow 18+ as long as you show ID. Is club space the kind of place where if I’m 18 would they still allow me in? Is the 21+ just for the post? Because I’ve known a lot of people my age that have gone inside. 18 btw Thank you
