Yang's moreish curls of roasted sweet potato are glazed in very light syrup. They are a locally celebrated mini chain but the shop opposite the post office is the original outlet.
Well, almost. In fact the founder, Yang Zhen Fa, started off in the 1950s selling these delights from the back of his tricycle on the streets of Taitung before starting a shop at all. Now they also sell tropical fruit ice-lollies (NT$35-55).
