i'd say the best sub place is Potbelly's but i don't know if they're all across the country or if they're just in the chicago area.

now some of you might not understand this but the best fast food place/restaurant is Portillo's. if you ever come to chicago area that is one place i can tell you that no matter what you order on the menu you will be satisfied with hot made on the spot food. absolutely delicious lol.
