I've been going to the SNFC since the late 80s. I used to walk by on a nearly daily basis, as I attended Sacramento High School (before Kevin Johnson bought the second oldest high school west of the Mississippi River for self aggrandizing political propaganda.) But I digress.
SNFC is a solid, old-school style food co-op. They have a legitimate option for being a co-op *owner*: the optional owner worker program. So you can pay for a membership, never work, and treat it like Safeway, or you can actually work to pay for your membership. (Unlike an almost totally fake co-op like REI, where you're just paying for a membership like Sam's Club or Costco.)
Anyway, the store. It has evolved a lot over the years, and is now a reasonably solid small-ish supermarket with a good selection of natural, organic, and harder to find vegan and non-traditional grocery options.
Is it kind of expensive? Sure. You're paying for more ethically sourced products, at a co-op, with a staff union -- and that's not free. But on any given day, an actually ripe, organic tomato might not be that much more than at Raley's or Safeway.
Great bulk section.
Unfortunately, I don't get there as much as I'd like: it's not super close, and I have a Sprouts closer that has a lot of vegan products (and super cheap produce, albeit kind of B grade.) But it's one of those places I know I can get certain ingredients and products at (like the large tub of Earth Balance) without just having to hope that Raley's might be carrying it.
Parking is atrocious, and always has been, to an almost comical extent. This is a place you want to ride, walk, or take light rail to.
SNFC is well worth supporting, and it'll be interesting to see their new location (as I understand it, being built now.)Pros: great bulk options, good product selection, righteous
Cons: slightly expensive
