I've been to Silver Crest Donut Shop. Once. I was disappointed that they didn't have donuts, or at least things you could legitimately refer to as donuts. Or much of anything, really, except a dirty 70s Bunn-O-Matic and a griddle and some bread and eggs. The diviest of dive bars, a strangely seedy and disturbing place. A sort of place you really don't see any more. I'd say it was Lynchian, but more in the Black Lodge sense than the Double-R.
It's gone now. https://sf.eater.com/2024/7/31/24210535/silver-crest-diner-d...
