Fire Tacos offers birria de res made with halal beef, braised with a blend of dried chiles and spices before being tucked into tortillas.[7][26] Their take stands out because of the halal preparation and a focus on Northern Mexican-style flavors using locally sourced ingredients.[26] When you order the birria tacos, the meat comes tender and juicy, often with a crisp sear on the tortilla and a side of broth for dipping that adds depth to each bite.[26] Commentators note that this truck-pop-up operation appeals to diners seeking birria while observing halal dietary practices.
