Most notable for me is when I go out to a restaurant in Manhattan I see many tables full of grown ups and seniors having lively discussions. In SF it's like that Star Trek episode where a virus kills off all the adults and leaves only children.
Population by age range, SF vs Manhattan:
20-24: 3.8% / 7.4%
25-34: 21.5% / 22.7%
35-44: 16.3% / 14.6%
45-54: 14.0% / 12.8%
55-64: 12.4% / 11.4%
65+: 15.2% / 14.4%[0] http://www.sfhip.org/index.php?module=DemographicData&type=u...
Manhattan has fewer young people with the means to dine out frequently. It's full of young people who want to be artists, fashion designers, etc... Most people who can afford fancy restaurant meals in Manhattan are older, more established in whatever their chosen career.
SF has a larger percentage of young people who are already wealthy (or middle class) from tech the sector. And thus more young people there dine out, more frequently.
