Had to check this one out. It sits off North Livemore, in Las Positas Court, in a parking lot behind the car wash. Been passing it by for a year now. Finally stopped and got a few tacos.
Too bad. The cabeza had nice texture, but no flavor. The pastor was fairly tough and chewy, which I like, but no flavor, which is pretty difficult for pastor. The chile verde was tender, but no flavor. All the flavor on these items came from the onions first, and the salsa second.
I'm gonna go back and try a torta ahogada, although I suspect there's likely to be less torta than ahogada.
