Basic details
Three Broomsticks is a place in Hogsmeade. The owner of this diner is Madam Rosmerta. This place sells Butterbeer, which was also the cause that made Winky the house elf sick, but Dobby helped with the cure.
Trip to Rosmerta
Somewhere in about 1998, Jacob’s sibling, the player of Hogwarts mystery asked for the Black Quill and his/her brother’s notebook. Later on, the player could drink butterbeer in Three Broomsticks after befriending Barnaby Lee. He/she along with Tulip Karsau went to Zonko's Joke Shop to get a Jumbo Dungbomb, and Bilton, the shop’s owner said that they had to go to Rosmerta and get Butterbeer 1107.
