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.
