Lately I've been lunching at Mi Pueblita, on 167th Street just west of Grand Concourse (between the 167th stops on the D and 4 lines). I got the torta first, which was pretty good - packed full of the usual stuff, including a nice jalapeno, but nothing spectacular. Lately, I've been eating the tacos, and they're really good. My favorites are suadero (goat) and carnitas. They're delicious with cilantro and onion, and you can douse them with guac and red/green sauce to your taste. If you're in the area, it's definitely worth a try.
