I went with some friends who live near this restaurant, it's on 4th Avenue and 12th Street in Brooklyn, and was pleasantly surprised. It looks like a dive from the outside, but it's attractive inside, and the owners are incredibly warm. The guacamole is excellent--creamy, well seasoned with lots of fresh cilantro. Their mole is really deep and smoky, and a friend ordered the steak with a soft taco in mole that was surprisingly flavorful and grilled rare as ordered. The bartender makes a mean Margarita. My only complaint is the music--too loud. Other than that, I really enjoyed it.
