Chicago people, gift help?

[redheadk]

My FIL works in Chicago in Willis Tower. My ILs still live near us, though, so he commutes back and forth and has an apt near enough to his office that he can walk to work. Any suggestions of lunch/casual places that would be good for a gift card? Nothing fancy at all, just something he can get to-go or eat while reading a book since he doesn't cook much for himself. Chains are fine, I just don't know what is available nearby.

For a nice steak, Gibson's is a couple miles north, easy cab ride, but it's good food. And always full of men on business trips (hence the area known as "viagra triangle").

Otherwise, it looks like there's a few Potbelly's nearby. Those are great lunch spots.
