Sigona's is a local(Redwood City & Stanford,CA) grocery store, actually it's more like a permanent farmer's market stand. Many of the fruits and vegetables are locally grown and organic. Their house balsamic vinegar and olive oil are great. It's a family run business and every employee I've interacted with has been super helpful. The best thing is to sign up for their e-mail list where they send you coupons for "free" food and cheese(sometimes wine) when you buy $30 worth of groceries.
