El Pollo Loco's Crunchy Chicken Taco provides a bit of a change from the typical fast food taco in that it has shredded flame-broiled chicken inside (I suppose it is makes sense, El Pollo Loco being a chicken joint and all). It's good but it's also more expensive at around $1.50 while still being the same size. Beyond that, it's the same standard cheese and shredded lettuce. The shell is freshly fried in Carl's Jr./Green Burrito fashion.
For the price the price though, I think most times, I would just eat their 99 cent Taco Al Carbon which is a chicken taco of the street taco variety (in a corn torilla with onions and cilantro).
