Point taken. National chains are great to satisfy a *need* for a burrito and the lack of knowledge of the burrito joints in the area. Moes > Chipotle > Baja Fresh in my mind. Never had Qdoba.
Anna's Taqueria is a burrito joint with restaurants throughout the Boston area. I am not from Boston, but visit quite often and found the place through the burritoblog.com. It fits the profile of a dive, but also the high traffic requirement you stated previously. I haven't been there recently enough to give a more detailed explanation, but am looking forward to my next trip.
