Here are my family's favorites - -
ANIMAL KINGDOM
We LOVED Flame Tree BBQ for lunch (counter service). The food is wonderful, and the tables by the water are so relaxing. We got happy meals from Restaurantasauras for the kids which they enjoyed - came w/ cute little dinosaur squirt guns.
This year, if the character meal at Hollywood & Vine doesn't become reality, we're trying the character breakfast at Restaurantasauras because our DS really likes dinosaurs (the "theme" of the restaurant), and we needed a character meal for him to go w/ the princess character meal for our DD.
DISNEY STUDIOS
We don't really have any "favorites" here. Last year, we ate at the Toy Story Pizza Planet for lunch (counter service). It wasn't anything special, but it wasn't horrible. The kids enjoyed it. We did the "Hollywood & Vine" Fantasmic Dinner Package. Neither DH nor I were impressed, and, this year, we're trying Mama Melrose's.
Also, I've read about the possibilities of a Toy Story character breakfast at Hollywood & Vine coming soon. If this proves to be true, we'll definitely try to get an ADR for that!
EPCOT
Last year, we ate at Sunshine Seasons for lunch (counter service), and it was okay. I think our kids would have preferred something else, but they did enjoy the dirt cup sundaes. I thought my steak/flatbread was good. I had some kind of fruit thing for dessert that was yummy!
We also did the PSB dinner at Akershus (Norway). We really weren't impressed w/ the food at all, but the character interaction w/ the princesses was very good. This year, I have an ADR for a PSB breakfast instead. (I may cancel though - either this one or CRT.)
We're also trying the character lunch at Garden Grill. And plan to try some of the World Showcase counter services for dinner.
My DH has been wanting to try San Angel Inn since the 1st time he went to Disney World, so we have an ADR for dinner there as well.
MAGIC KINGDOM
Liberty Tree Tavern Character Dinner is must-do for us, & I highly recommend it! This was one of our favorite meals from last year! The Declaration Salad was wonderful! (The mac & cheese was just so-so.) And the character interaction was fun too.
Crystal Palace Character Lunch is also a must-do for us! This was our very favorite buffet last year - so plentiful, so good! It was an excellent "break" from the park for lunch. It was quite crowded, so I'd suggest an earlier seating for whatever meal (breakfast, lunch, or dinner). The characters were good too.
We ate breakfast at CRT last year & thoroughly enjoyed it. This year, we have an ADR for lunch. W/ the changes at CRT going into effect in Feb, I may be canceling - especially if the other princesses aren't there. I haven't decided yet.
Our favorite counter service in the MK was Columbia Harbour House. The food was very good, and the dining room upstairs was relaxing & quiet.
RESORTS
Boma at the Animal Kingdom Lodge is wonderful! We ate there for dinner. And, while there are exotic dishes on the buffet, there is still plenty of other food to satisfy everyone. The desserts are amazing! I fell in love w/ the zebra domes! The kids' selections on this buffet were also quite good.
Trail's End Buffet at Fort Wilderness is also a good value. We ate breakfast there last year - nice atmosphere, good buffet (w/ Mickey waffles!), good value...
We ate breakfast at Chef Mickey's at the Contemporary Resort as well. Chef Mickey's is such a "Disney" meal/experience! Really fun w/ the napkin twirling & the characters! However, DH was NOT impressed w/ the buffet, and the characters seemed rushed. This year, we're trying dinner.
We also ate at Ohana at the Poly last year for dinner. This is a really nice restaurant w/ beautiful views of the castle from some of the tables. We really enjoyed our meal here, but, with the recent menu changes, I've read mixed reviews, so I don't have an ADR for here this year - especially since we wanted to try some new places. Even though we had an ADR, we had to wait about 45 minutes before we were seated.
Do you know which parks you'll be touring? On what days? Where will you be staying? What kinds of food your family likes? That will help as people make suggestions.
let me know of all the places I should not miss. The only thing I have booked is CRT. Any help would be very appreciated.
The best advice I can give is to check out the menus on allearsnet.com that Deb has compiled... click on dining and browse through them. If you have your park agenda all set, you can fit in restaurants which appeal to you. Or, some people decide on restaurants they want and then fit the parks around them! 
One of our favorites is 50's Prime Time. We'llbe trying Sci-Fi for the first time this summer. I've heard mixed reviews about the food...but they tell me the theming is awesome.
