We love both of them, but I think Tusker House is a good choice for the age range of your kids. The Mickey gang is great for everyone, and seeing them in Safari gear is nice. It is located next to the Safari, Pangani Trail, and Lion King show, so you could plan your day around it. We like to do late brft, to have time to get things done early, while crowds are low, and since they will at start changing over to lunch, you can try some of each, like brunch! They also may be offering meal packages there for the RoL when it begins, so you may want to consider that if they are announced.
