What's a ~reasonable~ amount of money to spend on groceries (in the Bay Area)?

What are you guys spending on groceries? Or what seems like a good food budget per week/month?

(I know this really varies between people, singles or families, eating habits, balancing convenience/healthfulness/cost, etc—- so I’m opening to hearing lots of different kinds of budgets for different eating/shopping habits! I’d love to get a sense of range and comparison!)
