Qdoba is my favorite of the local Baja Burrito/Cosmic Cantina/Moe's/Qdoba type restaurants that you can find in Raleigh (my favorite period is Chipotle, but it's not available locally). Why do I prefer it? They offer "lighter" fare. I'm not sure if it's lighter in terms of calories, but they actually have fajita burrito options available (skip the beans, and get veggies instead) and the cilantro lime rice just doesn't seem as heavy. The portions are really generous, and I've never been charged extra for asking for both sour cream and cheese (athem, Moe's). You can find $5 meal coupons in coupon circulars and books across Raleigh (any entree and drink for $5 + tax), and the student ID discount is a free drink. You don't get chips with your meal, but I honestly couldn't imagine being able to eat one after finishing one of the burritos.
