If you want steak, Shula's is excellent (and quiet). We had a later dinner here, there wasn't a single kid in the restaurant. It also wasn't very crowded, I think because we were there during free dining and because we ate so late.
California Grill's food is amazing. This is my favorite so far. There were some kids in the main dining area, but we were seated in a quiet wine room that was separate from the main area.
