Our kids ordered off the adult menu at RFC. At Sci-Fi, they had to order a children's meal and children's dessert(which was HUGE), but they were able to get shakes as their drinks and could order anything off the appetizer list. The kid's value kingdom lunch ticket was a really good deal at both of those places.
In case you're interested:
At RFC, we used two kids' vouchers. They ordered the combo appetizer sampler(had to use both vouchers for that one since it's like a double appetizer), one had steak and lobster, the other had steak and shrimp, and then they had the volcano dessert(once again, that counted as two choices). We had three kids, so they all split that.
At Sci-Fi, we used two vouchers and they got onion rings and chili as appetizers, chicken tenderloins and potatoes as their entree, and a cookie monster ice cream sundae type thing as dessert. Once again, all three kids shared, plus there was plenty left over for Mom too!
