I would say the best breakfast that I went to was, in terms of both quality and variety of food, was 1900 Park Faire. Also, the character interaction is some of the best in all of WDW, ESPECIALLY the Mad Hatter!

Other characters that appeared were Alice in Wonderland, Winnie the Pooh, and Tigger; along with Mary Poppins, who greeted guests outside in the lobby.
Cinderella's Royal Table would rank a VERY close second. The food was as good as 1900 Park Faire's, maybe even a tad better, but the menu is extremely limited, since every guest gets the same pre-plated dish. Character interaction was great here too.
Crystal Palace has a really good breakfast as well. This, too, is a character meal; with characters from Winnie the Pooh.
I did not have a good experience at Akershus, however. Service was not too great, food was decent but nowhere as good at the three restaurants mentioned above, and character interaction seemed rushed. The best part was meeting Mulan, who is not out too much, and gave the best interaction of all the characters there!
Hope this helps!
