The menu has a huge range of authentic-looking Mexican dishes. I don't feel qualified to comment on the authenticity. I will say that the food seemed very different from what's found in typical Tex-Mex style joints (in a good way). The portion to price ratio is rather small. Especially when it comes to the tiny tacos. I had the chorizo tacos. They came with a spoon full of meat, chopped cilantro and onions on each taco, which were about the size of my palm ($8.99). The tacos tasted ok but needed a little kick. The condiments (seasoned onion, salsa verde and salsa) brought to our table took care of that.
Next time, I would consider one of their platters for more variety.
