On the way back from Oxnard, my sweetheart decided to stop in SB and try to track down La Super Rica (for which we didn't have an address). We got off at Milpas, which seemed reasonably likely, found a phone book, and...no listing that I could find. (Anybody have the address?)
But a few blocks from the freeway on Milpas we did find Taqueria Bajio (and for those of you who know Mexican geography, yes, the owners are from Guanajuato) and had two really excellent burritos. The carnitas was moist and flavorful, but not greasy; the pork adobado was nicely spiced and perfectly done. Good (pinto) beans, too. What I think really distinguished their burritos was the quality of the ingredients. The prices are higher than the standard Mission taqueria (4.95 for the regular, 7.25 for the 'Bajio', i.e., with everything), but I'm guessing it works out the same by weight because these burritos were *enormous*.
They have a fairly extensive menu, including tortas and lots of breakfast dishes (chilaquiles, chorizo con huevos, etc.) that make me want to do a morning stop. Well worth a visit if you're passing through Santa 'we drive slow, and so will you' Barbara.
