Hi there, Eric, and welcome to planDisney! Gawrsh, thank you so much for stopping by with this great question.
Character Dining at the Happiest Place on Earth is incredibly magical and I'm so thrilled to hear that you and your party have reservations for Goofy's Kitchen! My two young boys always have the time of their lives swinging their napkins around and eating ice cream for breakfast (or brunch) at
Goofy's Kitchen. (Who am I kidding, Eric, I do too!)
Your reservation time is pretty much the exact time my family always makes for Character Dining too! We prefer to make dining reservations for a late morning, which ends up combining breakfast and lunch meals - a fantastic value for our family! The big meal also keeps my family pretty full until dinner. You made a great choice! While the menu can't be guaranteed, during your dining time you should be able to enjoy a bountiful buffet that includes all the mouthwatering menu items available for breakfast. Then my guess is that sometime during your dining experience there may be additional brunch items added to the buffet—like a carving station with turkey breast and carved beef sirloin roast. It's honestly the best of both worlds. I'm so excited for you and your party!
I hope this has been helpful for you in your planning, Eric, and that you and your loved ones have so much fun immersed in the Disneyland magic. Say "hi" to Goofy for me!
Warmest wishes,
McCayla
