I went to this place about six years ago and it was a pit. But they've fixed it up, and now have a very nice menu. And my second time there, it was almost full. So I'm happy to see they're meeting with some success as people are recognizing the improvement.
Fresh guacamole comes in a lava bowl, like many other places. The ingredients are balanced, and they make it with lime juice which keeps it interesting.
The alpastor is delicious, and like all the other Mexican places, you can get it in a taco, burrito, torta, huarache, etc. I chose the huarache, and it was delicious. Served on a thick tortilla with some beans, lettuce, tomato and cotija cheese crumbled on top. It was well presented and tasty.
The enmoladas (chicken mole enchiladas) were similarly well presented, and featured a rich black mole with a slight spicy kick. Served with rice and delicious black refried beans, it was a lot of food. I couldn't finish it. But not because of taste.
They also make smoothies and my favorite is the papaya/banana.
