Sorry, no. I've just had it at Mexican and Indian restaurants and prepared by a Jamaican friend. It seems to always be paired with strong flavors. The meat itself has a very familiar flavor -- it's reminiscent of goat cheese. I like it.

You're in Southern California Nancy. Look carefully at the Mexican restaurants in the Latino neighborhoods. The ones that serve goat paint the word "birria" on an outside wall of the restaurant. That's what you're looking for: birria. The restaurants that serve it are called something like birriaria, though I'm sure that's not exactly right.

Call around to Indian restaurants too. I've found it served in Indian restaurants in New Mexico and Colorado; surely you can find it in the California melting pot.
