While still being slightly "westernized", there is a admirable authenticity to much of the world-wide cuisine that is usually served by cast members that are from the various parts of the globe that they are representing. Together with immersive environments, small details, and even location specific background music, it's about as close to dining around the world as you can get, without going around the world.
Of special note, there are two well known foodie based festivals at Epcot that are not quite like anything else that we've found on the planet. The popular Epcot International Food and Wine Festival
takes place in the fall, and the ever "growing" Flower and Garden Festival in the spring. Both feature many kiosks that serve food and beverage pairings all along the World Showcase walkway, along with several additional "hard ticketed" special food and beverage related demonstrations and experiences.
