We'll be in Cow Hollow, but anywhere in the city is welcome. I was told by hounders in New York City, where we're from, that San Fran has better Mexican food than we do. We were in San Fran at the beginning of our vacation two weeks ago, and we tried two different places but were underwhelmed. We'll be back this Sunday to fly out Tuesday, so we'd like to give the Bay area one more chance. We're looking for authentic, straight-forward food to make us change our minds about which coast does Mexican better.
