I have only been once, but feel my research enables me to make some suggestions. Most we did go to last year.
MK-Fav is Pecos Bills, also Caseys Corner for big hot dogs, then there is Cosmic Rays which have a varied menu, which is good to please everyone. (Chicken ribs wraps burgers, etc)
AK-Flame Tree BBQ is great(Ribs chicken cornbread onion rings) but there are more authentic restaurants..I believe Yak And Yeti has a CS
Epcot-so many to chose from Mexico is on my to try list. UK has great fish and chips..also China has some great little counter service things. Then there is Sunshine Seasons which has a wide variety of foods. (near Nemo)
Hollywood Studios-We really enjoyed pizza planet (pizza and salad) and we ate at a place on the corner of sunset blvd I think it was. Had sandwiches that were HUGE and pastries. It was a nice change
Here is a link to the menus to all the CS and TS restaurants and their prices...

I've used it A LOT
Also, you can find TS reservations still. You can go to
www.disneyworld.com, then click on Plan and dining. You can do searches for your dates and restaurant and book right online.

Makes it easier then calling all the time!!!

You might catch a TS for your trip.
Have a great time!
