I've lived in walking distance from here for nearly a year and only recently tried them. There is a reason it is packed EVERY night. I'm mad at myself for not going sooner. Admittedly I haven't actually eaten inside but have ordered take out twice. Their tacos are some of the best authentic tacos in Charlotte. I could eat their queso fundido for every meal (but I'm a sucker for queso...but who isn't?!?!).
They always pack our bags with enough chips and salsa to last us a couple days. Speaking of their chips, they are perfect. Oh did I mention I also had their chimichanga, which I consider myself a connoisseur of, and it was definitely one of the best I've had. And that's saying a lot because if I'm getting Mexican then I'm definitely eating a chimichanga.
