The prices are the same at both locations. They appear differently because Goofy's you pay upfront, including tax and tip, whereas Storytellers, you pay at the table, so tax and tip are paid there, not main price. We prefer Storytellers over Goofy's. It is a little more sedate, and we like getting Mickey and Minnie.
I've done many breakfasts/brunches at Storytellers, and loved them. We also did Christmas dinner there the last few years and had excellent service and the food was great! Love getting the corn chowder.
