I have to give a restaurant shout-out to Mamacitas in Asheville, NC. I was hooked on this place from my first visit! The setup is like Qdoba (choose your ingredients), that's where the similarities end. All of the food is super fresh, there are some really unique ingredients (kale and sweet potatoes anyone?), and it's way affordable. Plus, it's a local business, which is even better! My favorite (so far) are the fish tacos with cabbage and fruit salsa. They even have a salsa bar...try the tomatilla! Last time I was there I took a couple crappy iPhone pics. Try Mamacitas ASAP!
