This year mark's the good old Donut Pub's 50th anniversary. The celebratory banner says, "Always fresh! Since 1964!" So maybe it's their 51st anniversary?
In any case, for the grand occasion, they've created a special Golden Anniversary doughnut.
The Golden Anniversary doughnut is rather elusive. Rarely made, it may or may not be available when you visit. I've been trying for weeks, and didn't get my Golden Anniversary doughnut until my fifth visit. (In the midst of my slightly obsessive quest, I dreamed about this pastry. In my dream, it was topped with flakes of real gold leaf.)
In reality, the rare delicacy is a regular doughnut glazed in yellow (for the "golden" part) with green stripes (for reasons unknown).
Was it worth the effort? Any visit to the Donut Pub on 14th Street is worth it. Next time, however, I'll stick with my usual honey dipped.
