Acre Coffee, based in Petaluma, makes a good cup of joe. All their coffee is French pressed, and while I usually grab a cup while flying through their San Francisco Civic Center location, when I'm in Petaluma, I slow down and nurse a cup at one of their tables as long as I can.
The walls feature a rotation of art from local artists, changing with the months -- landscape photos that show the peace of the desert at dawn, delicate collages of strong waves. The seating is reminiscent of a time where schools were in large one-room houses, and features (the ever popular) communal table, alongside desk-sized spaces.
