This link has a picture of the original Ollie's storefront, and gives their motto Everything But Subs, as does the store's web site. That strikes me as rather curious, because you don't get people in by telling them what you don't have, and I like subs. On the other hand, the menu has a number of things I definitely would eat though in the event I never knew the place was there.
As noted by commenter John R, the next incarnation is to be a chicken emporium: Wing Nuts.
