Tolerable but slow.
As others have noted, service here is insanely slow. Airport restaurants are, generally speaking, designed to be pretty quick affairs - after all, you might need to catch a flight. Problem is, even when this place had virtually no patrons but myself, service was abysmal - I basically had to flag down a waitress numerous times for even basic requests.
The food here is good, but nothing to call home about. It's better than the fast food offered elsewhere in the airport, but not significantly so. Frankly, I doubt I'd eat here again, if only because the service is so bad.
