Beef Fajita Taco (Fuel City, Dallas)
Where It's From: Fuel City, 801 S. Riverfront Blvd., Dallas, 214-426-0011
Why It's a Standout: The Picadillo (ground beef with diced potatoes) gets all the glory at Dallas's legendary 24-hour taqueria/car wash/gas station/beer store/swimming pool/zebra sanctuary just off the interstate. But Fuel City's beef fajita taco, sautéed with caramelized onions, delivers far more satisfaction. It's small – by local standards, anyway – yet every bite of the doubled-up corn tortillas contains juicy, smoky skirt steak and sweet browned onions.
