Bring wine to Drunk Bird

One of the tasks in the game requires you to talk to Drunk Bird, which will ask you to find and return a wine bottle to it.

After obtaining the key to the storage room by interacting with Drunk Bird, you may take the elevator in front of it to the lower floor, then proceeding up until a boarded up door and taking a left turn.

Proceeding deeper into the room, behind some boxes you will find 4 wine bottles, trace the path back to the elevator and you will be back to Drunk Bird's room
