All of the QS locations in Epcot World Showcase have different options. My personal favorite is Tangerine Cafe in Morocco - falafel & hummus & tabouleh, yum yum yum.
Sunshine Seasons in The Land in Future World also has a lot of different options for QS.
In MK, I second the rec for Columbia Harbour House. The tuna sandwhich, veggie chili, & clam chowder are all very good.
