I wasn't very impressed with the pianist and their lyrical abilities. The bar on the right was way crowded and not staffed accordingly. The bar up top on the left wasn't even staffed. I heard they don't like to staff the bar on the top left due to Customers using the stage as a site seeing balcony and preventing Customers from accessing bar.
You need to definitely keep both bars open and well staffed. Keep bouncers available to coordinate the crowd listening and hanging out.
