We have never done breakfast there but we just got back from having done 1900 Park Fare for dinner. We loved it! My girls (4/8) who are not the get up and do the "parade" type things at the character meals absolutely had a blast here. The characters were wonderful! They really spent a lot of time with my girls, despite how shy they are. So much fun. The food was rather good as well. Decent variety. I am very picky, but found plenty to enjoy.
This has been put on our must do list for future trips. We were the 3rd of 4th table the characters would visit after they entered the room, so we finished with them very early on in the meal, but wound up staying around and watching them with other people. One great moment of the evening was when one of the Step Sisters introduced a couple who had been married for over 60 years. She spent a great deal of time with them, as did the other characters who visited their table after.
For off park site breakfasts, we love Ohana. All the other character breakfasts we do are in the parks (H&V, CP, CRT, Akershus, Tusker House)
Have an awesome trip. Wish we were still there!
