Which nearby hotel?
The IC's Quills is the only halfway decent restaurant in the whole area, although it is no longer as good as it used to be.
You will find a food court landside in the terminal, with lots of options catering for a wide variety of tastes. Just don't expect gourmet food, and bear in mind that it can get really busy at times. Mid to late evening is usually OK, though.
Credit cards accepted everywhere.
