My dad's in town and wants to take us to a restaurant he remembers from at least 10 years ago... he says it's a hole-in-the-wall Chinese restaurant (seats 15-20 people) near the Embarcadero. There wasn't a menu; the chef would feed the guests. No reservations, so a line would form outside.
Is this ringing a bell for anyone? My dad would get a huge kick out of going there.
