Chase it down: Weekdays, parked in front of the Grocery Outlet, 2900 Broadway, Oakland.
What to get: Lengua tacos ($1.25 each) with cubes of braised tongue so soft they approach creamy, spiked with enough salt to make your palms sweaty.
Who’s in line: Groce Out shoppers, Pill Hill smocks, and grease jockeys with names embroidered on their shirts.
Street Meat will be a recurring feature about East Bay street food finds.
