You know, for what it is- this place is pretty good. I'd take it over subway, but barely. The whole wheat bread is awesome though- I've even paid for a few slices to take home once.
They do stand out in that they are FAST. No really, like super fast. When I was going to school in Tempe and only had a 30 minute lunch break, I knew I could call ahead while I was getting in my car, and by the time I drove 1.5 miles there, it would be ready and waiting. Beware- during lunch times it can be tricky to find a seat.
I wouldn't go out of my way to go there, but when it's around and convenient, it's a good option.
