For an airport catch-all place, this could work. It's located at an empty stretch at O'Hare, where a few under-served gates are located.
They have a market component with self-serve beer taps.
They have a bar.
They have food available, fetched from other restaurants in the area.
Technically, this could meet all your gate needs.
However, there was one person working there when I was there - to serve the bar patrons and check people out at the register and process food orders. One older gentleman fetched the food - slowly.
Service was a little abrupt and not at all quick.
