Yes! At shows where they know the crowd will be rough, they set up a barricade to protect the area. When it’s not barricaded, the front left of the stage has a slight angle next to the door to backstage and the bar on stage has disabled stickers on it to try to mark off the spot, so if people are blocking it just ask security to help you out!
It's more of a loft, but it's 21+ and there's stairs to it.
This venue is consciously working on continually bettering accessibility in their space.
