My personal favorite is the Art of Disney and Mouse Gear. World of Disney is great too, but it can be a madhouse sometimes.
Sometimes? I've never been in that store when it's not a sea of people.
Mouse Gear and then Mitsukoshi in the Japan pavillion.
Wouldn't call this the best, but in EPCOT, as you leave France and head toward England, there was (may still be there) to the left, down a path a gift shop where in the early 90s, I purchased the neatest beaded Mickey evening bag. Love this bag and still use it for dressy occasions.
