There are plenty of places to eat near ORD. Nothing I would nominate for a Michelin Guide, but some are not bad, and you can take hotel shuttles to reach most of them.

Harry Caray's (http://www.harrycarays.com/restaurants_rosemont.html) near Sheraton Gateway Suites is a classic Chicago Italian steakhouse. Giordano's (http://www.giordanos.com/) near Marriott Suites serves Chicago-style pizza. There are other options; let us know what you like.

There is a fancy movie theater, if you get in early (https://www.muvico.com/default.asp?t=210) - near Aloft hotel - and it has an Ok restaurant where (I think) you can have your dinner and watch a movie at the same time.

Finally, there are actually full-service dining places inside O'Hare domestic terminals.

Enjoy your brief layover!
