Is this a 21 and older venue for concerts ??

We're 21+ for all shows, but *can* do all ages with coordination from our booking team. Unless it explicitly says all ages, the show is 21+

Yes

Yes. All shows are 21 and up.

Yes it is. It's all one open area, 21 and older.

I am pretty sure as it does not have a way to separate the bar from the rest of the venue like how The Crocodile or other places might.

I am almost sure it's 21 and over but I'm not positive

Every show I've been to there has been 21+ only

I believe so. The bar portion wasn't separated in any way from the concert area, so I suspect it's always 21+.
