The one I like the best of these is Queso Grill in Lincroft (not a chain, though it seems like one in many ways). I have a definite preference for what to get: wet whole wheat burrito, pinto beans, no rice, grilled chicken, dos tomatillo sauce, green sauce, cheese, sour cream, chopped onion. I also have a set order for Moe’s (similar, but with more diced fresh veggies in it).
What I like about these places is that I can get what I like and avoid what I don’t. For example, I believe that rice inside a burrito is an abomination–a way to make you think you’re getting a lot for your money while giving you empty carbs. (For those of us who are pre-diabetic or diabetic, this matters.) When I design my own, I can skip the rice.
Chipotle, among its bad press issues, tends to throw stuff on before I can say (e.g.) that I want green sauce, not red.
When I go to an authentic Mexican restaurant, I don’t get burritos anyway.
