Went to la Palupa on St. Mark's off 1st Ave.last night, recently reviewed in the NYTimes. Without any warranties as to authenticity etc. (I've never been to Mexico), it was pretty yummy and a cut above most other Mexican food I've had in NY (not quite as good as Maya on the East Side, but a more comfortable, low key ambience than Maya). We had great guacamole, a tangy cactus salad with a chile lime dressing, chicken enchiladas in a mole sauce (no resemblance whatsover to ordinary "glop" enchiladas - more like a hearty rich mole stew with yummy chicken and chewy tortilla floating in it), and a succulent grilled pork in green pumpkin seed sauce served on a tamale. The tamale struck me as bland - maybe I'm not used to real masa tamales, and the pumpkin seed sauce was almost too rich - but the pork itself was incredibly flavorful. Service was very friendly and helpful, and the tab was $82 for two including tax, tip and three fruity margaritas (only so-so). Definitely worth a try.
