Introduction to Honeydukes Candy Shop: In Chapter 4 of Half-Blood Prince, Ambrosio Frum and his wife run a shop full of all kinds of sweet candies - Honeydukes Candy Shop (Honeydukes). The store not only sells a wide variety of candies, but also homemade fudge and super large chocolates, which are quite popular among Hogwarts students. Those snacks Ron and Harry ate on the train in the first movie are on sale here!
