I am sorry if I wasn't clear on my earlier post. They have similar items to Tonga Toast (though not exactly the same) at Boatwrights, Rainforest, and Kona Cafe. I would guess they are premade though, but you could ask if they could put somethign other than bananas in them. Here are the descriptions of the dishes from Allears.net:
Boatwrights:
Banana-stuffed French Toast - Banana-stuffed Texas toast, strawberry banana sauce and choice of bacon, sausage, or ham $7.99
Rainforest Cafe:
Tonga Toast - cinnamon French toast with warm maple syrup topped with fresh strawberries, bananas and walnuts, served with your choice of bacon or sausage $8.99
Kona Cafe:
Tonga Toast - banana stuffed sourdough bread, rolled in cinnamon sugar with choice of ham, bacon, or sausage $8.99
