This varies by show- it'll say on the tickets. I've been there for 18+, "all ages", and 21+ nights. If its a show for a band that appeals to a younger audience, there's a better chance of it being all ages.
I want to say at the Friday Duffy show, they IDed and gave bracelets but, I want to say they allow underage.
I'm not sure, but when I went to a show this past weekend, some people got brackets at the door and others did not. I'm assuming the bracelets were to mark they were 21. I don't usually drink when I'm out so this is just my assumption. It should say on their website.
