Where will you be?
Epcot: Biergarten
AK: Tusker House (we can't stand Yak & Yeti-tried it twice)
DHS: 50's Prime Time Cafe
MK: Liberty Tree Tavern or Crystal Palace
Resorts: Whispering Canyon
DTD: Rainforest Cafe
Liberty Tree Tavern in MK is my fav for lunch...their pot roast is so tasty....my son loves their cheeseburgers...and they have yummy desserts...and it is always a ton of food!!
If you're interested in doing a character meal, then schedule the latest Tusker House breakfast (w/ Mickey & friends). You'll probably be there long enough for the breakfast/lunch switch & you can try a lil of both.
Our favorite is Crystal Palace at Magic Kingdom. The food is delicious. It is a buffet with lots of food choices. Everybody in our family found some food to put on their plate Also, the character interactian is outstanding. The characters really spend time with your children. The characters are Pooh, Tigger, Euyore, and Piglet. I think this would be a good choice for you guys because it is a nice break from the park, and has great food/character interaction.
