The cheerful storefront signs marked “Bernal Bucks welcome here!” have become a familiar site along Cortland Avenue, the main shopping artery of Bernal Heights. Each sign promises a different perk for spending Bernal Bucks—cash marked with a Bernal Bucks sticker—the rewards ranging from a free pastry at Moonlight Café, to a discounted t-shirt at Fit Bernal Fit, or simply a free apple at Good Life Grocery.
