Charles Phan, the San Francisco chef credited as an innovator for bringing Vietnamese food to fine dining at his Slanted Door restaurant, has died. The restaurant announced his death from cardiac arrest in an Instagram post on Tuesday,

He also expanded his vision to new locations, including a Slanted Door in San Ramon and, more recently, France and Napa.

Phan, who started his career in San Francisco, is largely considered the inventor of modern Vietnamese cuisine in America.
