The food court in the convention center near the Marriott entrance has been remodeled and is open again. It must be on an event by event basis whether or not it's used now. The dining area now has a long window that overlooks the main hall (what in the past was the Artists' Alley hall). I got some pictures of it open at last winter's auto show.
