This is one occasion when it’s worthwhile to join the (mostly fast-moving) queue. Yes, you’ve tried cinnamon doughnuts before. And yes, there’s nothing particularly different about these. But you cannot discount the simple joy of eating a made-to-order doughnut rolled in a generous coat of cinnamon sugar, caramelised ever-so-slightly against hot dough. It’s no mistake that travellers have returned to Berry Donut Van year-on-year since 1964 — they are masters of the classic.
