Hi Grace,
You've simply made my day with your question. I love questions about Disney dining! Allow me to share with you recommendations for table service restaurants in each of the Disney theme parks.
Disney's Animal Kingdom: Tusker House has an amazing lunch buffet that includes both American and more exotic fare. Even though your kids are teens I bet they'd love seeing Donald and friends as they greet diners in this restaurant.
Magic Kingdom: Take a quick monorail ride outside this park to have an evening meal at the California Grill atop Disney's Contemporary Resort. Book this meal an hour before the Wishes fireworks take place. The view from this restaurant is unparalleled. If, instead, you're looking for a fun meal for the young at heart inside the park, try breakfast with Winnie the Pooh and friends at the Crystal Palace.
Epcot: Choose your table service restaurant here based upon your cuisine preference. If a German buffet sounds alluring, Biergarten is my #1 recommendation. If you prefer Mexican food, then the San Angel Inn has great food and atmosphere.
Disney's Hollywood Studios: I bet your teenage kids would get a hoot out of the 50s Prime Time Cafe or the Sci-Fi Dine In Theater. I guarantee they've never eaten in a restaurant like either one of these before.
Don't forget to call (407) WDW-DINE to make reservations for any of these table service restaurants 180 days in advance of your trip. And let me know if you need recommendations for quick service restaurants or excellent snack options by posting follow-up questions

Wishing you a truly magical Walt Disney World vacation!
