Restaurant for Offal, brain especially, in the Detroit area
Used to be a great place called Taquería Arandas in Detroit, on Livernois, that had them all on tacos, plus one named with a word I had never heard before. I asked them what it meant, and they said, "a little of everything." Unfortunately, they closed. If you're really up for this I would ask around the taco trucks and smaller places in SW Detroit (¿hay sesos? = are brains available?).
