A hole in the wall and some might not be comfortable with the crowd, but once you get over it, the food is sooooo worth it! If I remember correctly, the tacos are $1.38 each and you can choose from all kinds of meat including beef tongue. My favorite taco there is probably just beef. Also the tacos may look small, but they fill you up quickly. Even though I can wolf down steaks at buffets, 5-6 tacos is probably my limit here.
They also have a condiment bar and you can get grilled onions and peppers for free if you ask for them when you placed your order.
