The bone marrow taco fills a corn tortilla with rich birria beef stew meat and roasted marrow for an indulgent, fatty contrast. Chef Priscilla Curiel's version gained fame by pairing the stewed beef with creamy marrow that melts into every bite. The small shop's handmade tortillas provide a fresh corn base that absorbs the savory juices without falling apart. Diners note the luxurious mouthfeel and bold beefiness as standout qualities.
