After two visits, I think Natis compares well to the many other Taquerias on this stretch of Clark street. I first picked up takeout, and watch really struck me were the warm, crispy, deliciously lime-infused tortilla chips. The chicken and steak tacos I got were also good, featuring finely diced onion and cilantro along with lettuce and salsa.
Tonight my girlfriend and I ate there. The horchata was creamy and had a nice taste of cinnamon or some other spice. I enjoyed my tacos again, and my girlfriend got a vegetarian enchilada with very finely diced carrots, zucchini, and other vegetables, topped with cheese and sour cream, and in a very flavorful (but spicy sauce.) It was actually too spicy for her taste, but I loved it!
