The Saloon is an area accessible by descending down the stairs of a building in the Shrine Garden.
The Saloon is a western-style wooden building filled with boxes, tables, and various NPCs. To the left and right of the entrance are the restrooms. Mikan will only go in the women's restroom.
Directly north of the entrance is a bar with reddish floors. An NPC just north of the bar will teleport Mikan to the Billiard Zone when interacted with.
On the left of the bar is a small set of stairs to a green upper floor. At the end of this path, the right door leads to an empty room. The left door leads to a large red room. Heading to the right reveals a passageway into another room. In this gray room, interacting with the southern wall between the two boxes allows Mikan to enter the vent system. Walking through the vents will cause Mikan to fall into a room with 3 CDs. Exiting will send her out of the middle door in the green hallway. The door will be locked behind her and she can only re-enter by returning to the vent system.
