True Tonga Toast is only available at The Kona Cafe, but there are different "varieties" of it around the world. Boatrights at POR, offers a banana stuffed toast. Rainforest Cafe at AK also has banana stuffed toast, I've also had it at ASMo's food court. Now, they are all slightly different than Tonga Toast and aren't the same, but close enough if you don't want to travel to the Poly for breakfast.
