I recently stopped in for lunch and walked away a happy customer. Located in a strip mall, the restaurant has a number of tables and booths to sit at and decorated with a Baja California feel. Decorated in brick and wood, it is a warm and inviting place to grab a bite. I went with 3 tacos-Carnitas, Campechano and the El Tapatio (with avocado and cheese) all topped with onion, cilantro, and cabbage. All were delicious and the ingredients chopped very fine to get a complete taste with each bite. To accompany the tacos, there are two house made sauces that were both excellent. The only negative is that the corn tortillas were not made in house. Table service was fast and attentive. Take note, while there is a server, pay the cashier once you have the bill.
I'm not in Fitchburg often but I wouldn't hesitate coming back and trying more of their delicious food.
