Sam Wo (1912–2012, San Francisco)
The city's oldest Chinese noodle house operated for a century in Chinatown before health-code problems forced it shut in 2012.
Sam Wo closed after 100 years of continuous operation.
It reopened in 2015 under new ownership, preserving the institution's name and menu.
Illustrates that even storied SF Chinese restaurants can close and later revive, often under different hands.
