In my experience, I have never gotten a sandwich I would consider bad at Subway. But I have always felt that I could get a better sub if I went to any other sub shop. A sub that I would consider good. Subway defines mediocrity.

Jimmy Johns is still the only sub place I've been to that I've felt was just as bad as Subway. Its almost an accomplishment, the subs taste totally different but equally as mediocre and a place I avoid if I can.
