Whole Foods Market in SoMa area is different from the most grocery stores found in the downtown San Francisco: it has full selection of fruits, fish and meat, and no sodas. They stock organic foods, too.
For travellers, the fruit selection is especially nice; you can pick a lot of good stuff that does not need fridge in the hotel room. The store has an abundant selection of ready-made salads, sandwiches and other snacks, and the taste is much better compared to the usual plastic wrapped junk found in the grocery stores or 7 Elevens.
The store has a sushi counter with a chef and a bakery café.
