Restaurant Revitalization Fund

Has anyone heard of the Restaurant Revitalization Act?
I realize many shops had their best year in 2020 so this won’t apply but sit down restaurants take note.
This SBA fund is giving restaurants a check for the difference between gross sales in tax year 2020 versus tax year 2019.
I sold my mobile food concession a couple years ago but just talked to the new owner. His sales were down 100% in 2020 because all festivals were cancelled. He just received a 6 figure check equal to 2019 sales basically advancing a couple of socioeconomic tiers in one swoop.
There are requirements as to how the money is to be spent.
Here’s a link to sba regarding details:
