MK: Columbia Harbour House. I love all their seafood options!
EPCOT: Yorkshire Fish, La Cantina (fish tacos are my favorite), Crêpes À Emporter, or Les Halles. I do really want to try the Tangierine Cafe in Morocco, but sadly it was closed when we were there a few weeks ago.
HS: Docking Bay 7. The Batuuan Beef is SOOO GOOD!
AK: Flame Tree BBQ...Gotta love the pulled pork mac and cheese.
