We have tasty food (in Oakland), but its very different than NOLA food. Lucky for us, all the Cali farmland starts at the edge of the Bay Area. We've got space for local cows, oysters, cheese and produce, and all sorts of other stuff in the 50 mile radius (or closer depending). But probably the big thing, for Oakland in particular, is high quality ingredients/well-prepared stuff at moderately priced places. Like it is totally possible to get organic tacos, fast-food and ice cream. It is "normal" for places at all price points to have local ingredients. Which we all know in the US is far too rare these days. Basically it is either at the hole in the wall country place. Maybe. And the uber expensive 4 star place.
There is also a lot of cultural mixing too. Like don't be surprised if an all-american place has siracha, Mexican hot sauce, salsa and tabasco as condiments. Sadly Louisiana style hot sauce takes a bit more work to get on the regular table.
