What's you're favorite supermarket in San Francisco proper? I know that there are some excellent supermarkets in the east bay, peninsula, and north, but I'm interested where people shop here when not going to a farmers market, or specialty shops.
My favorite is Cal-Mart. I like the prices, especially the specials. Antonelli's, the butchers, is also awesome. Plus i find that they really have some of the best produce and pretty good prices, e.g. if I buy onions there they last for months. It makes up for when can't get to a farmer's market. Plus, I really like the old school feel of it.
What's your favorite?
