I think only restaurant chains that have a huge national presence or historically have a good takeout presence will be the survivors. We may be return to a “back to basics” movement in terms of restaurants in general in the next few years.
In Connecticut, with the governor has been consistently changing and moving the goalposts and dates on when things can reopen originally some mom-and-pop restaurants had signs in the window saying “closed due to coronavirus, we look forward to seeing you soon” or something to that effect. starting sometime in mid to late April several of them change the signs to simply stay “closed due to coronavirus.”
While subtle, those changes tell me that those places are most likely not reopening or if they reopen will be going out of business in short order.
