About a month ago I bought two warm, chewy churros from a very nice woman who'd set up a cart north of the Ferry Building, near a striped monolith and a parking lot. I liked the churros a great deal. I was hoping to eat them every time I went to farmers market on Saturday. On my next visit I looked for her but the weather was crappy and she wasn't there. As far as I know she has not returned since. Replying to my inquiry, the unpleasant woman at the farmers market information booth said, "She wasn't supposed to be there." Not a chowhound's reply. Can anyone tell me more about the Ferry Building churros woman and her fate?
