right.. when someone eats at a place and gives it a number of stars rating how good it was, it tells you the same about how good it is as instagram marketing. here's the point - you go to sf, get a place around you with good reviews, and the food is overpriced, overpresented, and average in taste.
The OP literally stated a reason to live in SF is the food. That's simply false. It's not poor quality, but it's no reason to live there. It's not better than in an average city.
