This is a sad story in a way. This man is not passing on this business to an heir.
I worked in a similar family run restaurant in my youth. My father had worked in the same restaurant in his youth as did three of my sisters.
The two brothers that I worked for had taken over the business from their father.
Sadly when they decided to retire none of their children had ever wanted to be involved in the family business.
The restaurant was bought by someone that shortly abandoned the recipes that had made the restaurant a regional favorite.
The bright side; it remained a family operation. A different family.
Our family had a favorite Chinese restaurant when I was young, got food from there all the time. The owner retired, and none of his kids wanted to run the place, so he had it torn down and sold the vacant lot.
