Has anyone tried Taqueria DF? They are on 5th & 22nd but deliver to the No. Slope area. I have to say they are the best tacos I've had in NYC. They are a very close second to those found from taco trucks in CA. We've tried almost all of the meat varieties of the tacos. The goat was very good. The delivery time is very fast & the prices can't be beat. The double-wrapped tacos are $1.00 each. The guac is very good as well. My only complaint is that they don't always include the lime & radishes. You have to ask for them. Check them out if you haven't already!
