MK: Pecos Bills or Columbia Harbor house
EP: Oh, so many, but I'll say Sunshine Seasons or Kring'la - pretty much anything in World Showcase will do you well.
HS: Um...well...Backlot Express is ok. I hear good things about Woody's Lunch Box, but I haven't tried it.
AK: Satu'li Canteen is great! Also, I like Harambe Market, but they may have changed their menu.
