* At the high end, Adam Parks of Victorian Farmstead (https://vicfarmmeats.com/) will sell you some awesome product for a sky-high price. He cuts his own meat, so you can get what you need if you are willing to pay for it.
* Schaub's in Menlo Park is a very competent butcher with very good product, also at (what seem like to me) high prices. I can get what I need from them, but it isn't cheap, and they clearly cater more to a different crowd, but they are better than the others I've found locally.
Disappointing: Harris Ranch is a massive producer of beef in NorCal. Yes, it is a factory farm, but it is family-owned and does have some pride, so I stopped there to see what was on offer. They don't even sell much in the way of what I'd call BBQ cuts (mostly high-priced steaks and some ground beef). Too bad, as they have the capacity to do better.
