Congrats!!
Some recommendations:
Yak and Yeti- AK
Via Napoli- Epcot
Mama Melroses- HS
Hollywood Brown Derby- HS
Cape May Cafe (only been for dinner) was very good!
Crystal palace (My all time favorite bfast buffet, its a must do every year!) this is a character buffet, but really if you're not interested they won't make it a big deal.
1900 Park Fare (great bfast buffet)
Earl of Sandwich at Downtown Disney is great!
Liberty Tree Tavern
Boma at AKL is a great buffet!
These are all sit down restuarants.
We're gonna have to do Crystal Palace and 1900 Park Fare for breakfast. I'm adding them to my list now, I keep getting reminded of them so they must be good! Thank you!
We honeymooned at WDW 5 years ago and we've been back 13 times since...and we live in Ohio! 

We both tend to not spend, and we BOTH are looking forward to the day we can dine there, again.
