Honeydukes Sweetshop
This store is a favorite among the students of Hogwarts because of the immense amount of candies that line the walls and shelves. The owners of the shop also make their own fudge and chocolate. It's no wonder the place is favored by everyone.
The cellar of the shop is the end of one of the secret passages that lead from Hogwarts to Hogsmeade. Should anyone say Dissendium to the one-eyed witch on the third floor of Hogwarts, this passage will open to them, leading them here.
