Also, word is that the portion sizes at Coral Reef are getting more reasonable (smaller), so sharing one meal between the four of you is probably not going to work out.
So that leave Sci-Fi. While some of the meals there are large enough to share, between you and your children, if that is your only large meal that day, and your twins eat as much as my DN1 did this past January, you and your spouse may leave the restaurant very hungry.
