We've been to CRT and Ohanas pre-plated. I think the price is the same as buffet. The selection is less.
www.wdwig.com menus section will tell you all the food they have.
At CRT, the table has pastries and fruit are ready for you to eat when you are seated. Children get pancakes/waffles and a few other breakfast type food. Adults have a choice of 'healthy' fare like musli and fruit OR my fav, cream cheese french toast, creamy potato, bacon, sausage and eggs. I always request more french toast and occasionally a bit more bacon. Yes, you can ask for more, it's an 'all you can eat' type of thing. Sort of like a limited buffet, but the server brings it to you.
Ohanas started us off with a pineapple bread, very nice! They didn't give us individual plates, instead we got a wok/flying pan filled with breakfast food ~ eggs, bacon, Mickey waffles, sausage, there was other stuff too, can't recall. I asked for more waffles for my 2 year old, he ate 4! dd liked bacon, she asked for more bacon.
I like both buffets and pre-plated. We enjoy the quality of food over quantity any day. We aren't the 'fill your plate until food falls off family' so pre-plated is a nice change to a buffet.
I have funny buffet rules for myself: no food can touch (avoids mountains of food), half the food on my plate has to be fruit or veggies. I tend to get full and I've eaten well. I'm much happily trying only a tablespoon or two of everything than mounds of only a couple things.
