People used to cook a lot more, in the last 30 years or so they are eating out a lot more.
Some people are learning to cook during the epidemic, as much for entertainment as anything else, and some of them will keep cooking. Also some eat-in business will go to delivery.
It isn't hard in principle to hibernate restaurants since the main cost is labor. You give the workers enhanced unemployment insurance, the restaurant stops paying the rent, the landlord and/or mortgage holder might get a bailout the same way the employees get unemployment insurance, etc.
Some would say that we are eating too much as restaurants and it is making us fat, causing diabetes, etc. Women entering the workforce has had a number of ecological impacts on the society which are rarely discussed (Liz Warren's "Two Income Trap" is a counterexample.) Dual income couples are not just paying more for mortgages and restaurant meals but for also for insulin and payments to their morticians are coming sooner.
