Mythos (IOA)!: Delicous sit-down, you'll want to plan some extra time for this meal.
Confisco's (IOA): sit down at little more than counter prices, more casual than Mythos.
Thundering Falls Terrace (IOA): counter but has a nice outdoor patio where you can watch people at the end of the JP ride.
HRC: a bit loud inside but good food/resonable $.
Margaritaville: Huge nachos, good veggie burgers, excellent mango margaritas. Always our first stop for food on arrival day!
