Chef Mickey's does sort of spell Disney! It is very fun, very lively and the food has always been very good for us. Something about being in the Contemporary with Mickey and friends is sort of sacred lol.
That said, Cape May is sort of my favorite now and would get my vote. Its still a lot of fun, but much quieter and not as hectic. Mickey isn't there however. The food at Cape May I think is better than Chef Mickey's and again, its a lot of fun but not the fun on speed that Chef Mickey's can be.
1900 Park Fare is also really good food, they have an omlette station (CM's and Cape May do not, they have plain scrambled eggs and an egg dish that has like cheese and maybe ham but not omlettes). We don't do this one as much anymore becasue I enjoy the dinner there even more than the breakfast and we are hooked on Cape May!
O'Hana is not my favorite breakfast. I enjoy ithe setting, but the skillet they brought didn't fill up my husband and 13 year old and they never did come by in time to refill it (it is all you can eat and when you have a teenage son, all you can eat is beyond belief!). I would go again, but there is something to be said for the variety of a buffet. It was a fruite plate, then a skillet with bacon, eggs, sausage and potatoes and some breakfast breads. Just not enough variety in the food department for my family.
