Do they have seats I'm disabled with a bad leg and can't stand through a whole concert

I went with a disabled guest and the was a roped off area for wheelchairs and folding chairs for helpers

The only seats I remember were at the bar. You should call them and let them know that you're disabled but would love to come in 'IF' there is a place where you can sit. I'm sure they will let you know about all their seating. Or accommodate you because business is business. So, if you're going to be spending money there, then I'm sure, just like any business, they'll want you to be there.
