ooops!
According to the nearest Shakey's, the one on Sepulveda is closed and has been for a while. I first attempted to call the location, prior to contacting the one on Balboa. I sure wish someone would remove any and all notices regarding the one on Sepulveda (in Panorama City) since it is no longer open. Maybe we wouldn't have to be wasting all our time finding this out.
