“It is above average. Not that far above average.”
In my area (San Francisco Bay Area), Five Guys is the most expensive of the national burger chains. A standard meal of cheeseburger two patties), medium fries, soda and sales tax will run you about $23. Obviously, McDonalds and Burger King and the like are a lot cheaper, but even local cult favorite In-N-Out will charge maybe $13 for something similar to that $23 meal at Five Guys. Also, the truth is that there are many dine-in, full-service restaurants where a similar meal can be hald for a few dollars less.
I lived in CA for about 15 years. Never really “got” the In-N-Out cult thing. The food was OK, but not remarkable, IMHO.
