Sounds like you live in an expensive pocket, like near beach or a special neighborhood.

Use google to find gas near you it lists out prices . I was just in garden grove yesterday. Gas was 4.80 to 5.20. If you are driving a sports car that needs premium gas your going to pay more to enjoy more .

I took my extended family out in garden grove , 7 people for dinner at $130 before tip to a decent sit down place. McDonalds and Taco Bell at 6-10 for a meal.

Even near Disney in Anaheim prices are better than you listed out. I can grab a full meal at Denny’s for about 12-15.

When I first moved to ca I lived in a cool community where I could afford rent. Daily life was so expensive I was riding the bus an hour to get groceries.
Now pay more in rent and less in everything else in a boring place. Moving a few miles will make a difference for you.
