Been to both, many times. IMO Kahaunaville is a knock-off of the better themed RFC. While the fountain show is nice, when there's a "storm" at RFC and the animals move, it's a lot more entertaining. RFC does not have the game area that Kah has. BUt RFC does have a huge gift shop so you'll spend the same or more money than you'd spend on the games. I think portion sizes are bigger at RFC (remember this and share - unless you can take home leftovers!) But overall value for money about the same. In both you're clearly paying extra $$ for the entertainment. These are town of my DD (9) favorite restaurants.
