I got lucky and parked half a block up from the bar. The neighborhood is a little rough, but if you park on El Cajón itself by the bar, there are two clubs with people standing outside so there shouldn't be any trouble. If you live close by, get dropped off by an Uber or Lyft or bus it there and Uber/Lyft home after hours.
There's no parking lot but it isn't difficult to find street parking within a half mile if you're good at parallel parking
