I'm a creature of habit so all I can tell you is the chicken burritos are fantastic. Me and a few other people at work pick up lunch from here once a week. You can't beat a huge burrito for less than $6 that is ready in about 5 min.
Unfortunately I haven't found anything else in the area to compare them to. Although when I was at UMass Amherst I frequented a place called Bueno y Sano that served the best burritos I've ever had. If only they would open up a restaurant around here.
