The Tonga Toast is very sweet AND very rich -- it's basically deep-fried. If I order it, I share it with someone who gets eggs and we split. That works out well.
Kona has wonderful breakfasts and good service. Wonderful coffee if you are into coffee. My family always goes there on our last morning, after check-out, because they serve late and we can be seated around 11:10. They have a wonderful fruit platter that is my favorite. You get a piece of banana bread and a piece of a big muffin and the most delicious fresh fruit. It comes in a pineapple!
FYI, some of the a la carte items at Kona are actually CHEAPER than the breakfast items down at Captain Cooks, like the cereal. My daughter doesn't eat much at breakfast and always orders Fruit Loops, which we do not normally have at home. They charge less than they would downstairs at CC for a small box of cereal plus a milk container.
If you are in a rush, CC is a great place but if you want a nice breakfast in a lovely setting you can not beat Kona Cafe!
