Telling what is open and closed in New Orleans

I was getting a tire plugged the other day.  While I was waiting, I walked around the block and discovered this nightclub.

The man who plugged the tire was done in about 5 minutes.  I asked him if the L&R is still open for business.  "Of course it is," he said.

I explained that I'm fairly new here and I still have a hard time recognizing buildings that are abandoned from ones that are still viable.  "You'll get used to it," he said.

I'm thinking about going on Monday for the red beans.  This is a traditional Monday dish, hereabouts.  A lot of bars offer it.
