Driving back and forth between Fresno and San Francisco has several disadvantages. But one must turn lemons in to lemonaide. As you pass through Tracy and decide on the last cheap gas stop before the Bay Area, look to the Grant Line Road Exit just past the Valero Station. You'll come to a strip mall at 2242 Grant Line Road and Taqueria Maguey. It's the real deal here. $1 Tacos and there's a chips, salsa, and pickled bar for all you condiments. I think this is pastor and carnitas tacos. The Best!
