From the Story
Discovered in Harry Potter and the Prisoner of Azkaban
Honeydukes is a sweet shop in Hogsmeade. The shop is also the location of a passageway between Hogwarts and Hogsmeade, which starts in its cellar. Shelves upon shelves of sweets line the walls from Every Flavour Beans and Fizzing Whizzbees, to the more bizarre Cockroach Cluster.
