Concert age limitations (if any) or rules should be listed when purchasing your ticket. If you're still unsure contacting the ticket seller.
Not that I know of. If there is an age requirement ot should be listed on the event link.
I haven't seen an age limit for the venue, just for purchasing alcohol there
Or call your ticket provider
as far as I've experienced, there is no real age requirement. the best you could do is contact the venue agency for further details.
