Is it odd that we refer to San Francisco as the city? If you live in the Bay Area and say: "We're going into the city," everyone would know which city you meant. Not Oakland, not San Jose, not Walnut Creek. These cities are all nice. But the city is San Francisco. And it's fabulous.
While I was in town my parents took us into the city for breakfast at the farmers market at Pier 1. I had never been to the farmers market in SF and oh my goodness, talk about yummy overload. If you are ever in the city over a weekend, go on Saturday morning. You won't be disappointed. And if you see a booth offering Red Wine and Cherry Scones, buy one. And savor it.
