Mickeymomm,
My older son's (almost 7) favorite character meals are:
Chef Mickey's - He loves it. My husband and I are not huge fans of the food (although we have only done dinners here). I don't find the food bad, but there is much better at Disney. When I have so many credits, I don't mind using them on restaurants that aren't necessarily my faves but that my kids love.
1900 Park Fare - Tigger, Pooh, Mary Poppins, Alice and the Mad Hatter. I enjoy the food here as well and enjoy the character interaction. My younger son was very excited to meet Alice and her character handler noticed. He whispered something in her ear as she approached our table, and she actually sat down next to my son and talked to him for quite a bit. The Mad Hatter is hysterical.
'Ohana Breakfast - Lilo, Stitch, Mickey and Pluto.
Garden Grill - The restaurant slowly rotates over the Land ride at Epcot. Chip and Dale are pretty funny. Once again, my husband and I didn't believe the food was the best, but the atmosphere was fun for the kids.
His favorite non-character meals are:
Teppan Edo (Epcot) - This is a hibachi-type place, so watching the chefs prepare the food at the table provides a show to entertain the kids. The staff is incredible! They made "kid" chopsticks for my older son while my younger was sleeping. My younger son woke up, saw his brother's treasure, looked upset, and before he could open his mouth to complain, a waiter was at our table making him a pair. A waiter also made origami for my kids. My kids are pretty picky eaters, but they love the food here. They get the chicken and dip it in what the chef refers to as the "Japanese Ranch" sauce.
Sci-Fi Dine-In - The tables are actually in cars, and they have cheesy old sci-fi clips playing in a dark theatre. I could see that some kids might find this a bit scary, but neither of my boys were even remotely bothered by it. They thought it was a fun atmosphere.
California Grill - We had a table by the window looking down at the Magic Kingdom. My kids loved looking down at the Magic Kingdom and enjoyed getting to have steak. The signature restaurants provide more unique kids meals and kids desserts other than the typical sundae. My husband and I love this one as well.
Artist Point - Our waiter was great with the kids. Once again, a unique dessert where they got to paint (with a brush and edible paint) a white chocolate Mickey puzzle. My 2-year old wasn't on the dining plan and they brought him his own mini-puzzle to paint free of charge. This is my husband's favorite restaurant on Disney property so far.
'Ohana Dinner - There is entertainment for the kids, and we got to view the fireworks from our table. My husband and I have found the meat here to be a bit over-cooked in our 2 experiences here but many absolutely love it.
My kids pretty much love all the character meals, but my favorites would be Akershus at Epcot (have only had breakfast here), Donald's Safari Breakfast at Tusker House in Animal Kingdom (awesome food), and the 1900 Park Fare Breakfast at the Grand Floridian. You didn't mention what gender your kids are, but my two boys really enjoy the princess meals. (CRT, 1900 Park Fare Dinner, Akershus). Despite being "all boy", they both enjoy the princess movies and enjoy meeting the princesses and getting to actually talk with them.
Some of my husband and my favorite non-character meals are:
Liberty Tree Tavern (the pre-plated dinner is good but we love lunch here)
The Plaza (great sandwiches and awesome ice cream desserts)
Kona Cafe Breakfast
Tutto Italia (my husband thought this was the biggest surprise of our last trip - he was expecting Olive Garden but thought this was delicious and I agree!)
Yak and Yeti - this is my husband's favorite table service within a park and this is his one "must-do" each trip
California Grill
Artist Point
I'll post our ADR schedule in a bit.
