Day or night, the indoor-outdoor café Blue Danube attracts a diverse array of coffee lovers, writers and Richmond District neighbors. Decorated in vintage chairs and hanging chandeliers, the café is one of the most unique in the city. Offering mimosas, coffees and a selection of juices, Blue Danube is the ideal place to kick back and read. Inside, you’ll find a large bookshelf with journals full of drawings and poems from visitors throughout the years. If there’s nothing intriguing on the shelf, a few doors down is Green Apple Books, one of the most popular used bookstores in the city. Wi-Fi is available, for a fee.
