The place is called goofys candy cauldron I believe. Im not sure about making candy bars but they do have a made to order section , where you fill out a form and then they make what you want. You can do dipped apples, pretzel sticks, marshmellow sticks, rice crispies and a few other things. First they dip them in chocolate, caramel or white choc...there might be more selections, then you can pcik toppings like oreo , butter fingers , sprinkles etc.
Oh and yeah it is over by rainforest cafe.
