I like Jimmy John's. It's usually a pretty darned good sandwich. My favorite is the Italian Night Club.
So, while they are freakishly fast and the food is good, I personally think it's a smidge overpriced for what it is, and it's considerably noisy (even when there are no patrons). Sounds like the employees are having fun at least! Temp. control is also on the cold side too, but not too big a deal.
Also, I like the bathroom signs! Will post one...
