BEST HUARACHES EVER! I'm not Mexican but I've lived in Houston all my life and Mexican food is second nature to us. I love their Huaraches (which is like a large home-made tortilla used as a tostada and topped of fwith your fav meat/veggies. I recomment trying the rajas con queso (which is sliced poblano peppers and cheese) topped with lettuce, tomato, and more cheese. The Menudo, the Pozole, the Tacos, the Tortas, and anything else i've had there is great and super cheap. I've never been to the Biss location but I always go to the Irvington location and its great! I'm a usual customer for Saturday morning breakfast.
Pros: Great food, inexpensive, fast
Cons: Somewhat crowded at times, not the nicest ambiance but what do you ask for when you pay $5 for an entire meal!
