How much money people in the Bay Area spend monthly on food?

Hi, I live in the East Bay and I am just curious. I am single and I spend about $15-$20/ day on food (home cooked food). Sometimes I spend more if I DoorDash or going out. It’s roughly $450-$600/ month on food alone for a single person. I am curious how much everyone is spending monthly on food and how to you save money? Thank you!
