But even Red Robin will be expensive. The cost of a burger in San Francisco does not equal the cost of a burger in Texas, Florida, Wisconsin, Colorado, etc. There's a core price, then there are all kinds of state and local taxes too. The taxes are a big part of what makes Chicago expensive, although not nearly as bad as San Francisco.

You ordered from Door Dash. I've never used them, but the two I'm familiar with (Uber Eats and Caviar) both increase the price of food and often add a delivery fee or service charge (whatever that is) too. For instance, the burger price I quoted from Five Guys is about $1 more if I order it through Uber Eats. Realistically, for the 3 person meal I quoted above, the price would go up by about $10-$15 + delivery tip on Uber Eats. But if I want the better price I have to get in my car and drive 4 blocks to Five Guys for curbside delivery instead .
