Better Than Most, Still Just A Sandwich
I've been meaning to try Jimmy John's for a long time. Since I was at the county office to renew my car registration today, I gave it a shot.
My overall impression is that it's a good sandwich. They seem to have a good variety, the quality of ingredients is good, and they had it done and handed to me within a minute or two of ordering it - even with the long line of people in front of me!
On the other hand... it's still just a sandwich. I'd choose Jimmy John's over Subway or other sub-sandwich shops that we currently have, though.
