I'm in downtown San Francisco for work, and I'd like to bring a few goodies back to my wife in DC. We were here in April, but she was pregnant and couldn't enjoy many of the foods she normally loves (specifically chocolate). I was planning of stopping at Tartine on the BART ride back to the airport tomorrow afternoon, and I'm going to try and hit the farmer's market at the Ferry plaza today to pick up some more beans from Rancho Gordo. I would be appreciative of suggestions for some places I could visit to pick up other (semi)-nonperishables within a 5 - 10 minute walk of my office at California and Davis. Thanks in advance.
