Yeah, the lines are long, but that's a sign that the food must be worth it, right?
So yeah, you have to wait awhile for some delicious / cheap tacos (or whatever item you decide to go with). The $1 tacos are still just as fantastic as I remember them being, and the $2 quesadillas are right up there with them.
The pico seems a little spicier than before, but still good. I noticed that it's now "cash only", which is pretty inconvenient, and hopefully that's just a temporary thing.
If you're in or near the area, this place is a must. The food is better than authentic.
