I like many of the Disney Breakfasts...Iheard alot of good things about Cinderells Castle, but haven't been and am not sure if your DH will enjoy the Princess characters.
Depending upon where you're staying - Cape May at the Beach Club is one of my favorites. It's a yummy buffet that includes Mickey Waffles. It's a character breakfast with Minnie, Goofy, Chip & Dale. It doesn't seem as "hectic" as other character breakfasts to me. If you're staying at Beach Club, Boardwalk of Yacht Club it's very convenient to get to. If not you can get there via EPCOT or DH. If you go before the parks open I suggest a bus from your hotel to DH and right in the front there's a boat from DH to Beach Club.
I also heard good things about Ohanas at Poly and am trying it when I go in Sept.
It depends if you want a quiet or more active breakfast. Chef Mickeys is usually loud. Obviously non-character breakfasts are more peaceful.
What resort are you staying at?
