Sunnydale is a town that doesn't exist in the real world, but it is the locale of Buffy the Vampire Slayer. It's a small, one Starbucks town, according to Cordelia and is two hours from Neiman Marcus, according to Buffy.
The Bronze is the only club ever actually seen or mentioned in Sunnydale, but it is assumed there is more than one because of Cordelia's statement in the first episode (WttH):
Hamilton Street (mentioned in WTTH)
In the fourth episode (TP) Weatherly Park is mentioned. Buffy goes there (and lies to Giles about it) to find Claw Guy for more information on Dr. Gregory's death. There are a lot bums sleeping there. This park is never mentioned in the show again.
Sunnydale Funeral Home, first seen in NKAB.
Sunnydale Zoo, seen only once in The Pack.
Delta Zeta Kappa House - first clue that there's a college campus in Sunnydale (RB). It's Crestwood College, not UC Sunnydale
Kent Preparatory School. Just outside of town. (RB) Brittany Oswald, junior at St. Michael's, disappeared a year ago. So did Kelly Percell, sophomore at Grant. (Other schools in Sunnydale)
Sunnydale Press - Xander reading the paper in (RB)
Pop's Pumpkin Patch - in Halloween, kills vamp while another vamp tapes it for Spike
Partytown - where Cordelia got her costume in Halloween - everyone else went to Ethan's.
Sunset Club - shut down club where Ford and his Vampire Cult meet (LTM)
There are forty-three churches in Sunnydale (WML2)
