“We applied for the PPP (Paycheck Protection Program) and heard nothing back from our bank or from anyone,”
They needed a new bank. I know a company that applied and got the money in less than a week. I don't know how much will end up being forgiven but the loan allocated enough for 8 weeks of payroll and rent as promised by law.
If they operated at half capacity it would definitely bridge the gap between having one unprofitable cook and nothing. I suspect though they saw the writing on the wall that road travel will be down substantially this summer so it may not make sense to re-open just in time for the off-season, especially if they are nearing retirement in the next couple years anyway.
There is a restaurant in the same straight in my home town. They definitely qualify for assistance but if they don't build up a profit war-chest through tourist season, they won't make it through the winter.
