I'm probably posting about a place that is WAY before your time, but maybe one of your Aunties might know. In the 70's a friend introduced me to dim sum. With my first bite I was in love...yum. We went to a place on Pacific just west of Grant in Chinatown. It was called Fu something or something Fu. I know that's not much help but it was my first and regular (when in S.F.) dim sum pig out. It was a small place and the dim sum was delivered on trays. When crowded you had to sit with others and one time we got lucky and sat with a nice Chinese family (mother, father, 2 daughters). He introduced us to a really exotic dish (or so I thought at the time)--duck feet! Maybe someone in your family can remember the name of the restaurant? It was on the north side of Pacific.
Another question: in that same time frame, there was a bakery around the corner, just north of Pacific on Grant. They made the BEST coconut macaroons...at least, that's what we called them. I frequented that place for several years until one time it was no longer there. Did they move? go out of business? My children could hardly wait until I opened the boxes of cookies so that they could have samples!
