I'd say Sunshine Seasons, too, but honestly it's going to depend on what you guys like. For example, the new food cart serving artisan-style grilled cheeses by Test Track looks like it could be a great, unique choice--but they only serve a couple of things. Similarly, most of the places in the World Showcase only sell a couple things, but they are unique and yummy (Tangierine Cafe and Yorkshire Fish and Chips are great examples of that). Les Halles has more options, but they seem to be variations on a theme--that theme being (mostly) strongly flavored cheeses and pastry/bread. So I'd definitely read all of the menus to scope it out based on your family's likes and dislikes. Our family usually snacks around Epcot--we split things from counter-service and if we're all having a larger meal at the same time we end up, usually, at Sunshine Seasons (just for the sake of the variety).
