Jersey Mike’s..,Think of one notch above Subway.
If there is a Firehouse Subs near you go there.
Jimmy Johns is good also.
I used to like Quiznos. Got turned off by their deceptive advertizing and inconsistent quality.
One store would be good, another lousy.
Jimmy Johns is good - love their gargantuan (for $9 though?).
Problem with them is the portion size. By FAR the smallest of the sub chains.
