The crowd at Birrieria Tijuana is here for one thing: Tijuana-style birria. The beloved beef stew comes in many forms. One you have to try: quesabirria. Quesabirria is the meat and solid goodness of birria taken from the broth and married with melted cheese and a hot tortilla, all eaten as a taco. The stew’s broth often comes on the side, coiling steam just like birria bowls, for spooning to your mouth or direct sipping between rich bites of taco.
