Gosh, there is so much to eat with a kid that age. We just went with DD3 this past Sept.
We went to
CRT lunch (princess)
Akershus lunch (princess)
Chef Mickey's breakfast & dinner
1900 Park Fare breakfast(Alice, Mad Hatter, Tigger, Pooh & Mary Poppins)
Crystal Palace breakfast (Pooh, Tigger, Piglet, Eeyore)
'Ohana dinner
Teppan Edo dinner
Sci-Fi lunch (I wouldn't recommend this as much, there are better meals)
All were great. DD especially loved Chef Mickey's & the princess meals. 1900 Park Fare for breakfast was fun. I've heard great things about 1900 Park Fare for dinner, which is Cinderella, Prince Charming, evil stepmother & stepsisters. 'Ohana & Teppan Edo were both non-character, but fun for kids. Cape May Cafe has a character breakfast & has a Clam bake for dinner. I think we might try both of those. Crystal Palace was great, but I think it won't be open when you are there.
I totally recommend getting ADRs for when you are there. As it's not worth having the dining plan, unless you make all your table service meals and you probably won't be able to walk up to a lot of good places. Good luck and have fun, it's such a good age to take a girl!
