She would have to exit and go back through TSA
Yes
There is a McDonald's in the International terminal (#5) available for take away that you can get to without passing through TSA.
There is nowhere for sit down dining at O'Hare Airport, but the Hilton across the street has some places.
No.
No. You have to go through security. Ever since 911, security is very strict. Plus the restaurants are basic fast food places.
The only places to eat at O'Hare are past security, which requires a ticket. As the other poster said, Rosemont has many nice restaurants. It's a short drive. Take Bessie Coleman to Mannheim instead of the expressway.
Not really. Better off meeting her off airport property. Maybe in Rosemont. Lots of restaurants there
