Just got off the Fantasy after dry dock.
Enchanted Garden had a breakfast only one morning, so yes it has been phased out. It was the traditional sit and be served, they will make omelettes to order, deliver drinks etc. Then you are free to go to the buffet area at the back of the restaurant to get the usual - pastries, fruits, eggs, sausages, meats, cereals, etc.
They still serve the full sit down breakfast at Royal Court all of the days, including the day breakfast is served in Enchanted garden. Though that day it is considered a Brunch, and opens later in the morning, like 10am.
Enchanted Garden also no longer serves a buffet lunch on embarkation day. This has been the case for a while.
The character breakfast is in Animators one day during the cruise and requires a ticket to experience.
