As soon as the coast is clear, hundreds of new ones will open. The number of people who want to quit their job and open a restaurant is enormous. With the competition bankrupt, an unusually large number of the new places will become successful.
Why would anyone want to risk everything NOW on a restaurant that can be shut down at will by the state or local authorities for any perceived health scare?
Now that they got this power they will continue to use it again and again.
You would have to be a nut to open a business in New York.
