Head south on Stockton and turn left on Clay Street. Sam Wo at 713-715 Clay Street has been serving Chinatown since 1907, making it one of the oldest restaurants in the neighborhood. The original location was famous for its dumbwaiter that carried food between floors and for Edsel Ford Fung, a legendarily rude waiter who became a local celebrity.
The restaurant closed in 2012, reopened in 2015 at this Clay Street location, and the food is still excellent. Order the jook (rice porridge), the chow fun noodles, or the barbecue pork with rice. Simple, cheap, and satisfying. This is a good place to sit down for a real meal if you’re hungry, or just peek in and keep walking.
