While I realize this is The Marco Gutierrez Nightmare, the town across the Raritan River from me--New Brunswick-- now has a thriving Hispanic population, and with that scene come the tacos and burritos and enchiladas and posole and mole Oaxaqueno and empanadas and chorizo . . . I could go on and on, but I'm already salivating; anyway, here are two recommended options, one upscale and one incredibly cheap:
1) for the best tamales in town-- and they only cost a buck and a quarter-- head to Punto Y Coma; it's on French Street right in the heart of Little Mexico, and you'll have to dust off your Spanish to order, but it's worth it . . . great tacos al pastor, too, in homemade corn tortillas;
2) for something fancier, if you're looking for a real night out, then head to Esquina Latina . . . this place has more of a weirdly lit dance-club lounge feel, but the sangria is amazing and the food is really good too . . . especially the empanadas, just don't pronounce them "empanyadas," or you'll sound like a rube (as I did).
