I think our fav is the Kitchen at HRH. They have a kid room in the back where they can wander off and play while you sit at your (nearby) table and enjoy your meal. Kids can go back and forth to get their chicken fingers! (We usually eat in the area of the Kitchen NOT near the kid room as our "kid" is big and usually prefers to stay at the pool while eat).
Another great location for a family meal is Mama Della's over at the PBH.
