Backbar? (Wrong forum before, sorry)

Do you need to have tickets to be able to get in to the backbar? My friend and I were wondering because I know there is that back entrance next to the parking lot, unless I am totally confused and that bar is a part of the venue for ticket holders only.

Thanks!
I answered this in the other forum:

The status changes night to night. On nights when a show is sold out or close to sold out you will likely find the Backbar closed to patrons without a ticket. However, most other nights it is open to the public.

I guess if you want you can call and ask on any particular night. (202) 265-0930
