Chef Mickey's breakfast is one of our favorites (we've eaten there the past 4 years).  The breakfast buffet is standard breakfast fare, nothing special, but good nonetheless.  We enjoy the fun, open atmosphere with occasional monorail passing by overhead.  As a pp stated, the characters will dance around to upbeat music encouraging patrons to wave napkins over their heads.  One of the benefits of CM is that it features the Fab 5: Mickey, Minnie, Goofy, Donald & Pluto.  We've always had good character interaction at CM - we've never felt rushed.
