Not to be confused with Taqueria Mariachi in Trenton. This is a Mexican/Guatamalan restaurant in the Chambersberg area of Trenton, housed where formerly there was an Italian restaurant. They have retain all the old decor, including the mural of Italy.
I have found all of the food to be quite good, but what I have really enjoyed have been some of their soups. The first (whose Spanish name I can't quite recall) is made from trip and cow's feet. The broth is rich and spicy, the tripe wonderfully chewy and the connective tissue on the cow's feet is heaven for those who like gelatinous food. It is one of the best soups I have ever had. They make nice thick tortillas. The other soup (served only on weekends) is Sopa de Res, aka beef soup. A real country dish. Not spicy at all, full of vegetables, a broth that is unbelievably good (it compares favorably to good pho), along with pieces of oxtail and short ribs.
I haven't tried any of the other soups, but plan to sample them.
They don't have dessert, but make a great horchata which seems to very from time to time.
