21 and over only?

Ticket will say whether show is 21+ or all ages. Even if all ages, there is a 21+ section with access to a bar on the main level.

Usually the left side of the stage is all ages, then you can pass through an id check / wristband gate to the larger right side of stage area that contains the bar and 21+ area. I've been to at least 5 shows there all like that. When you buy tickets it should say. Call venue box office to confirm if in doubt. Good luck, have fun.

That always depends on the show. Jonathon Davis was all ages.

Both times i have been there it was all ages but it should depend on the band/artist playing.

Depends on the show. Many have an underage section.
