Amanda,
You are so right, I love the dining questions!
Let me give you my top couple sit-down dining options, by park, for a family with boys. That way you can decide based on where you are. I have them in order of preference. Also, I have skipped any 2-Table Service credit restaurants, but I have some favorites there too, if you want to write back and ask!
Magic Kingdom
Crystal Palace
Chef Mickey's (leave park, take monorail to Contemporary Resort)
Whispering Canyon Cafe (leave park, take boat to Wilderness Lodge)
'Ohana (leave park, take monorail to Polynesian Resort)
Liberty Tree Tavern
Epcot
Biergarten (dinner)
Rose and Crown
Le Cellier
Les Chefs de France
Teppan Edo
Restaurant Marrakesh
Hollywood Studios
50s Prime Time Cafe
Mama Melrose
Hollywood and Vine
Animal Kingdom
Yak and Yeti
Downtown Disney

Write me back and I can offer more ideas, especially if you let me know where you are staying.
Have a magical (and delicious) vacation!
