Tenderloin, San Francisco - Where are the grocery stores if I move there?

I wouldn't live there if you paid me

There aren't any large grocery stores in the Tenderloin. You'll find a lot of small markets: Central Tower Market at Turk between Hyde and Leavenworth, Golden Gate Market, Hyde Market.

If you're interested in a larger store, then you can visit Whole Foods at California and Franklin or either Safeway that is within a mile (one on Geary and one on Market).
