Honeydukes

Honeydukes is a sweet shop famous for its chocolate and its many, wonderful and wild sweets. It is located in the wintry, all-wizarding village of Hogsmeade, in Scotland, and is frequented by students and Professors alike; indeed.

It is run by Ambrosius Flume and his wife, although other workers have been hired before. It is probably the most visited location for students on Hogsmeade Weekends. The cellar connects to a secret passageway from the third floor of Hogwarts, one of the original secret passages out of the school.

As she's only been able to visit Honeydukes outside of school, Obderedria Pienas owls letters and candy orders to the Flumes from time to time. The shop also gets many orders around holidays like Halloween and Valentines Day.
