All are indoors besides the Yak & Yeti counter service location, which is mostly shaded. If you're referring to the Yak & Yeti table service restaurant, that is inside.Like to get out of the heat to eat or at least be in the shade: ABC, Yak & Yeti Cafe, Skipper Canteen, Columbia Harbor and Liberty Inn?
Liberty Inn at EPCOT is indoors.Of the places you listed, the Yak & Yeti quick service is outdoors. I'm not certain about the Liberty Inn if you are referring to the quick service at the American pavilion in Epcot.
Every other place you listed is indoors.
