When we took our dd2 and dd3, we were fortunate to be on the deluxe dining plan (dh won the trip!!!) so we did a character breakfast every day...here is my opinion...
Tusker House(AK) - delicious! we did this breakfast twice
Characters: Mickey, Donald, Daisy, Goofy all in safari attire
Food: buffet - assorted breads, bagels, jellies, spreads, fresh fruit, scrambled eggs, bacon, sausage, frittatas, kids buffet, waffles, carving station with ham (YUM), oatmeal, donuts, pastries, fruit cobbler, and more, definitely something for everyone...definitely american but somewhat of an african flair.
Jungle juice is a must, service is very friendly, they have a dancing parade with all the kids, it is really fun, even my dd2 got into the parade, a server from another section took her and held her hand, it was so nice! Plus, this gets you into AK early, and right on the other side of the Tusker House...the Safari!
Princess dining in Norway(EPCOT) - good, we did this breakfast twice, too
Characters: Belle, Jasmine, Aurora, Mulan, Snow White
Food: cold buffet with fresh fruit, jumbo strawberries, cheeses, meats, salmon with the trimmings, croissants, danishes, spreads and jellies...hot family style platter with scrambled eggs, bacon, sausage, and cheesy hash browns. entire meal is all you can eat, the server will refill your hot platter.
This is a nice atmosphere, the princesses are great, all stop and talk for a while, very relaxed atmosphere. This is a bonus because included in the price is a photo with a princess, both times we went it was with Belle. They present your picture package to you while you are dining. Very nice.
Chef Mickey's(CONTEMPORARY) - ok, once was enough
Characters: Mickey, Minnie, Donald, Goofy in chef attire
Food: buffet - fresh fruit, bagels, breads, spreads, jellies, waffles, pancakes, frittatas, omlets, potatoes, corned beef hash, oatmeal, donuts, eggs, bacon, sausage.
It is so hard to get an ADR here, we had one for 7:45 am, the line is horrendous, the place is so loud, the food is about mediocre, the characters are rushed, our service was lacking, the only good part was seeing minnie mouse, because she was not at any of our other breakfasts.
Crystal Palace(MK) - ok, once was enough
Characters: Pooh, Eeyore, Piglet, Tigger
Food: buffet - omlet made to order station, pancakes, waffles, pastries, fruit, breads, oatmeal.
This seemed like the most disorganized place we ate in all week. Food kept running out and it took a long time for it to be replaced. I missed out on a few items I had wanted because they were empty. That being said, the characters are great, I have a picture of my girls dancing with pooh in the lobby, and we were in the potty when one of the characters came by, so our waitress brought him back when we sat down. Very nice service and characters, but the food was pretty much yuck!
Hollywood & Vine Playhouse Disney(DHS) - great, a fave for sure!
Characters: Leo, June, JoJo, Goliath (little einsteins and jojo's circus)
Food: buffet - food was delsih! bagels, toast, pastries, eggs, ham, bacon, sausage, corned beef hash, yogurt, fresh fruit, oatmeal, grits, cereal, pancakes, waffles.
This was total traditional american buffet food. My girls were so excited to get yogurt for a change, and all the buffet food was fresh and delicious. We had an early ressie, so my dds got to interact with the characters a lot before it got busy. They came to our table 2 or 3 times, and were great posing for pics! They do a dance every 15 mins or so, and all the kids get up and dance with the characters. Both my girls loved it. This place surprised us, for some reason I wasn't expecting much, but it ended up at the top of our list.
Conclusion:
I say if you are only doing one, and your dd3 is a fan of Little Einsteins or JoJo's Circus, go with the Hollywood and Vine. The food was great, service was great, characters were so nice, kids got to dance and play. Also, there was not too much that interested my dd2 and dd3 at DHS, so that breakfast was part of their entertainment for the day. I would suggest an early ADR (8am or so), then head over to the Playhouse Disney show, which starts at 9:30. We all had a blast!
If your dd3 is not a fan of the above, I would say Tusker House for the traditional characters or the Princess in Norway for the princesses.
I can't speak for the Cinderella's castle breakfast because we did not do that one, but we did eat dinner in the castle, and while the ambiance and surroundings cannot be beat, the food couldn't be worse!
