Yes, there are general concessions as you'd expect at a music venue (hot dogs nachos, etc). For many events there is also a full service bar.
Yes. Food and drinks
There are food and alcohol vendors in the main lobby area. Pricey but decent quality.
I would not recommend eating here as my girlfriend got very sick at the concert that we attended here! The place was awesome but no food places near it at all.
