San Angel in Epcot was DD's and DH's favourite last time, so there.
Sci-Fi Diner in Hollywood Studios for theme.
O'Hana for breakfast with Stitch for DS.
Chef Mickey's for breakfast requested by DH.
I've managed to get into T-Rex at Downtown Disney which I missed out on last time for DS.
I've also just booked Rainforest Cafe on an evening at Animal Kingdom for new shows there.
We're staying at Beach Club, so have also booked Cape May Cafe for breakfast and an evening meal, plus Beaches and Cream for tea one evening.
Others we haven't been to include Mama Melrose at HS, Crystal Palace for lunch (did breakfast last time) and character breakfast at Grand Floridian, which I suspect will lead to me having bad thoughts about wanting the stay there... 
We are on DDP this time. Last time we had DxDDP and it was too much - ate all the snack credits and had loads of meals left. Felt like the whole time was eating! We are foodies, but there was a limit even for me.
This time, we are in walking distance of Epcot and the boardwalk, so will wander out for quick service options rather than book in loads of sit down meals. I also like ordering pizza from a local takeaway as a treat when we're there. They bring it into the lobby for us.
