We have one of those Dollar taco trucks a few blocks from my house. I've never bought anything from there because I'm not into "real" Mexican food but I've heard it is good.
A friend brought me a big burrito from there that had steak? in it that was pretty good. If I ever tried it again I would get it without the rice. I'm not a fan of rice in a burrito.
I usually get the Al Pastor Tacos. About 5 of them!!
