Everything is on the same level and there are no stairs sans one step to enter the live house. The bar is in the same room that the bands play. The stage is a moderate height, so if you are in the back, you can still see the band. The room is spacious however there is little to no seating.
the door to get into the live house is a bit heavy so may require a bit of force to open.
The bathroom is in a separate location than where the bands play. However, you do not need to go up or down any steps. It has a western-style toilet, but the bathroom itself is rather small, so there is not much room to move around.
