In 1997, the vampire Angel threatened Willy while the bar was closed but then apprehended by Kendra Young who, after a brief battle, locked Angel in a cage within the bar, only for Willy to save him from the sunlight that would shine over the cage space through a window.
A year later Willy and the bar was attacked by the Sisterhood of Jhe, causing some destruction.
In 2000, the paranoid Riley Finn threatened a human patron at the bar just for walking while he made a scene because he found Buffy Summers associating in a place full of demons. Despite his previous anti-demon stance, Riley drank at the bar months later while another bartender was present. There he drowned his sorrows and nearly consumated with a vampire named Sandy.
It was presumably destroyed along with the rest of Sunnydale by following the Battle at the Hellmouth.
