Oakland, CA is a strong contender if you step back. Especially for one of a Stephensonian-styled second-wave cyberpunk. It even plays a part in Neuromancer.
It has its dark parts along with strong facets of common cyberpunk themes: drastic social stratification, the social acceptance of regular drug usage, urban decay meets technocratic renewal, a renewed definition of suburbia, and a greater acceptance of non-binary genders.
I like it, especially because there's a strong artist population there, and a common theme in cyberpunk is showing what the non-techies' life is like (to contrast it to the main characters' lives), and it's quite often artists.
