We have never dined there (as we always have the kids) but my choice would be Victoria and Alberts ( I think they have a Chef's table, too) for something super nice; next would be the Wolfgang Pucks Dining Room at DTD; and third would be Kiminos Sushi Bar or Kona Island Sushi Bar (as we both really like sushi)> I think the last has a kids club nearby which would make it convenient.
