We're pretty spoiled when it comes to farmers markets in San Francisco. There is, of course, the Ferry Building—the arguable Big Daddy of all markets everywhere (well, other than the one in Marin, and the one in Berkeley... we've got much produce to go around in these parts)—is certainly worth a weekly (or tri-weekly) visit, but there are an amazing number of little market gems all over the city.
The Grove Street Farmers Market, holding court between Divisadero and Broderick every Sunday, is one of my favorites. In addition to the usual bounty of fruits and vegetables, you can stock up on cheese curds, fresh honey by the jar, and cheese curds; not to mention burgers grilled to order.
Seeing as this is a farmers market, is is the produce that really has us coming back every Sunday. Last weekend, summer was still in full swing, despite the chilly wind coming off the Pacific. Piles of tomatoes, corn, and baskets of strawberries beckoned from the stalls. Apparently, this year we're in for a long season of summer produce thanks to consistently warm, dry weather; as a vocal lover of all things tomato, I consider this to be the best kind of news.
But eggplants are making appearances as well, alongside a wonderful selection of root vegetables including Japanese sweet potatoes, beets, and carrots.
