The Sunflower Natural Foods store is the only one of its kind in Yuba City. They carry organic produce, bulk foods, the hard to find items, lots of vitamins and bulk herbs, natural personal care products and house cleaning products. You can special order items, too. They have monthly sales and a knowledgeable and helpful staff. My only complaint is that their bulk food section isn't as big as I would like it to be.
The store also has a restaurant located in it that serves lunch. The food is really good and very affordable.
