"There are a number of exceptional carts in Portland selling quesabirria, the Tijuana-style beefy, cheesy dish and all of its relatives. Quesabirria carts generally sell a few standards: The namesake dish, something like a thick, beef quesadilla; crispy-tortilla’d vampiros, smaller quesatacos, and, in certain places, dishes like birria ramen. The quesadilla at Birrieria La Plaza — essentially quesabirria — comes stuffed with melty quesillo and braised beef, best dunked in a side of the beef’s braising liquid." - Zoe Baillargeon
