Taqueria Laredo on Washington near Shepherd is a good place for a quick taco. Everything is served cafeteria style but is very fresh. I generally get the spicy fajita but the brkfst taco's are good along with the barbacoa. Other dishes of notwe are mole chiken taco, chicharrone's, and chicken and noodle tacos.
Also I mentioned El Taconazo recently and have to mention again because the fajita taco's there are as good of taco's I have ever had. All they have is beef and boy is it done right. From downtown take 45 N to patton and take a left. Take Patton to Fulton and go right on Fulton. It should be 1/4-1/2 mile on the left on the side of a tire store(the tire store is an old garage looking place). The area could be considered rough but I feel ok when I go.
