Every time we have visited this location in Oakley, CA, the quality of food is always consistently good. The atmosphere is homey, comfortable, good for families with children, or large groups. The portion sizes are always generous, so be prepared!. Service is very good and the servers are attentive to refilling your drinks or getting whatever you need. Black Bear Diner is noted for having HUGE bear claw pastries, along with their individual fruit pies (black berry, my favorite) which are delicious. Make sure to have some of their fresh squeezed orange juice for breakfast!
