"Wifi: Yes Mercury Cafe in Hayes Valley is bright and unpretentious—exactly what we want in a neighborhood coffee shop. Come first thing in the morning for their baked scones (they will sell out), or stop by afternoons and order a slice of homemade apple pie. Mercury is one of the more relaxing places to work, but charge up your laptop beforehand—there aren’t a lot of plugs (nothing like the impending stress of 8% battery to cramp productivity).
