I live in a European city with only a handful of buildings above 5 stories tall.
Population density is too low for anything but a few restaurants and a grocery store anywhere but in the city center and a few larger shopping centers around the outskirts. The mix with businesses give mostly lunch restaurants that are closed in the evenings and it's just as much a ghost town as anything else after hours.
It’s not because of 5 stories not being enough. I live in Berlin where almost all buildings top out at 5-6 stories and there are restaurants and shops all over the city.
