I love Jimmy Johns.
Better than all others (subway, I'm looking at you), IMHO. Food quality, taste, experience and fastness are all high points! I love that they deliver, and that they're open late.
But I think my favorite part (aside from the yummy food) is the friendlyness of the staff. They always greet you when you come in, and say goodbye when you leave, and I have yet to have an interaction that's not pleasant.
Also, they really are freaky fast!! One time I ordered to deliver at the Art+Design building, and they were there *less than 6 minutes later*. How is that even possible??
