After 4 or 5 visits, I can't really rave enough about this new place in downtown Lowell. It was supposed to open at the beginning of February, but inspection delays held it up until 2 weeks ago. It was worth the wait, everything I have tried has ranged from good to excellent. The staff is friendly, and the few minor service problems I had on my first couple of visits seem to have worked themselves out with a couple weeks experience.
I have tried so far:
Tacos: I have tried chicken and pork with red chile sauce. The flour tortillas are obviously fresh made, sour cream and guacamole is free and the meats have been succulent and plentiful. They also have chicken w/chipotle cream or mole, and carnitas pork.
Chiles Rellenos: The best I have had anywhere, very different almost ricotta-like cheese filling, with an eggy batter. Served with excellent refried beans and rice.
Torta: I have only tried the beef barbacoa. Moist, shredded beef, similar to short ribs in consistency on a huge toasted french bread roll. Probably a third of a baguette with lettuce, tomato, guac, and sour cream. Easily enough for two lunches.
Ceviche: Very fresh and tangy with chiles, tomatoes, avocado, cilantro and lime. Served on a fried tostado with more lime and avocado on the side. They also have shrimp and crab ceviches.
Burrito: Tried the fajita chicken. Not huge, but very nicely rolled, not overstuffed and falling apart. Very good.
The menu is really extensive, with tamales, fajitas, sopas, and all the usual suspects(enchiladas, quesadillas, etc.) They are in the process of getting a liquor license so margaritas are on the way. They also have mexican coffee, candies and pastries, and 4 kinds of salsa. They seem to be doing well so far, but there is another Mexican place across the street, so check them out now, I don't think you'll be disappointed.
