I'm Italian, there's plenty of stellar places with no online presence and endless customers.

Any city with either an actual city center, an historic center or touristic area. Any restaurant that is in a major business area.

Any neighborhood were local zoning is not a thing and local restaurant can be open. We have a lot of tapas or marisquerías places in Spain that are almost only visited by people from the same neighborhood. I like fish and seafood but don't want the smell of it in my kitchen the next day, whenever I want to eat fish I go to some place selling that and I don't need google maps to find one in my neighborhood.

Also world of mouth is still a thing in many places in this world. Reading HN feels sometimes like a weird parallel universe were people would never open their front door nor meet and to people.

Yes, this is exactly the thing. Our restaurant is in Spain, and what you're saying is very true, which is why Google Maps, Instagram and Facebook tends to be important, as again, half (~guess) the people who arrive found it via Google Maps or Instagram, the rest are people who live nearby.
