MK - Pinnochio Village Haus - I am addicted to Figaro Fries and the turkey bacon pannini was really really good. Plus, my dd loves the turkey pinwheels with grapes.
Epcot - I always get nachos at the Cantina in Mexico, so I guess that's my favorite, but I really like Tangerine Cafe too.
MGM - Nothing really does it for me here, but I guess I would try that new one, Flatbread Grill or something like that? Near Backlot I believe.
AK - Tusker House. You get the most bang for your buck here I think.
Resorts - Pepper Market at CSR is really a lot of food for what you pay and it's worth it to visit the resort.
