Most food we serve at Cafe Mason is homemade, prepared from the scratch with quality ingredients. We carefully select our own produce daily, organic whenever available to make a wide variety of California cuisine dishes served for breakfast, lunch and dinner. We're open 24 hours a day, so stop by to sample our seasonal crepes, fresh pastas and classic diner dishes.
