My favorite restaurant in the Bay Area is “cheap” at around 25$ per person.
My favorite restaurant where I line now (northern Arizona) is cheap at $8 a person, and tastes mostly the same. There’s also no reservations, and it doesn’t take 3 hours to get to because of traffic.
Making 60k a year in not-SF is like making 200k a year in SF. Except 60k is far more attainable basically everywhere.
It has nothing to do with San Francisco itself. If I was a millionaire, San Francisco would be the place to live (or at least tied with NYC or Seattle)
