Tortas aren't as common in Denver as burritos, tacos and enchiladas, the dominant symbols of this city's defiant obsession with Mexican food. But the mighty torta, Mexico's sandwich star, is the focus of Tortisimas, which opened on Federal Boulevard in 2013. The bread -- called birote -- is procured from a local bakery and serves as the base for just about every topping you can imagine: ham, chorizo, pork chops, frankfurters, eggs, chicken, steak, pineapple, pickled onions, avocado, chiles, tomatoes and, of course, melted cheese. Tortisimas features nearly thirty tortas, all of which are served with a small cup of blood-red chipotle sauce. Housemade aguas frescas and desserts, including a chocolate flan, are also part of the Mexican journey.
