Cape May is good, but the brkfst buffet is rather limited compared to other WDW brkfst buffets. Cape May is very calm & relaxed and the character interaction is very good, but now there are only 3 characters there: Minnie, Goofy & Donald.
Chef Mickey's is one of our favorites: very fun/upbeat atmosphere, good character interaction with the Fab 5, and a nice brkfst buffet with a very good selection.
Ohana is another one of our favorites - we enjoy the polynesian theming & it's nice because the food is served to you. The brkfst menu is limited, but the food is good. Ohana has a relaxed atmosphere, yet is alot of fun. The character interaction is very good: Pluto & Stitch are hilarious + you get Mickey & Lilo.
