Tamales are $1.50 and enchiladas go for about $6. But, we're here to talk tacos.
What to get
Hands down the carne asada (bistec) tacos; I wouldn't rate this place as one of my top choices but definitely WORTH A VISIT if you're in the neighborhood and hungry. The chicken and the carnitas tacos are also worth an honorable mention, not very dry and not very greasy.
What NOT to get
Two things, the first is the vegetarian taco, because you can make this at home (although people seem to like them). Second, the lengua taco, I am a big fan of this taco and well I was a bit under-whelmed. I can't stress enough how much of a snob I am about this taco because when it's made well it's Jimmie Walker Dy-no-mite!
This place is definitely CASH ONLY but the truck is conveniently parked in front of an ATM.
