Is there a bar inside

Yep.

Yes. The west end (standing room only seating) has a bar open to everyone plus there are bars restricted to people with tickets in that section. I was in section 207 and had to walk through a huge beautiful, carpeted lounge area with tables and couches and 2 big bars and bathrooms. I was very pleasantly surprised. Due to Covid restricting crowd to 25% it was wide open- no waiting, no lines, no crowds.

Yes

No, not *a* bar. Multiple bars!

Yup

Yes. Several bars everywhere.
