So many of these restauranteur articles. One thing is certain -- it is not the governments job to fix this. This is the market playing out in a pandemic. Restaurants are non-essential and faced with this level of distress should perhaps consider shutting down and coming back when the market can support them. Unless one has deep pockets or the will power, I'm not sure how many can survive.
With the thin margins, most can't afford to pay more and many customers aren't either regardless of how much they want to eat out. I love restaurants and it has been sad to see some of my favorite ones shut down -- hopefully they'll be back!
