I’ve tried tacos from this truck a few times and I can confidentially say I will come back for more. The truck is across from California hospital medical center next to the USC family practice building. The truck is serving the neighborhood and hospital employees. You will see long line during lunch hours. Food is decent. Price is very reasonable. They provide very fast service so that’s something I’m always looking for. Los Marcos is definitely a must try if you’re around the area.
