Want big flavor without spending big bucks? Look no further than El Ultimo. Tacos start at $1.50 and ratchet all the way up to $1.75 for el ultimo on thick flour tortillas. This place is known for its breakfast taco selection, but you can never go wrong stopping by on your lunch break (shouldn't be hard, their usual spots are right outside the loop). Pick your meat (go for the de chicharron y barbacoa, trust us) and have it topped with salsa verde, grilled onions, cilantro, white cheese, and avocado slices.
