We frequent the Los Tacos on W. Sahara on our lunchbreak.  The tacos come plain and there is an extra charge for the cheese, etc.  However, the prices are still reasonable.  I bit into my chicken taco yesterday and the meat was so moist it dripped juices.  It was not grease, but chicken broth.  The pico de gallo salsa is really good too. I love going here for lunch. My co-worker said her steak taco was awesome too.  The music was a little too loud for me though.
