A burger chain that has a very limited menu (double double, hamburger, cheeseburger, fries, milkshakes, sodas) with a secret menu (animal style: extra spread, mustard grilled patties). It's very good, but Californians praise it to death, therefore its also very overrated.
Do you want to eat at In-N-Out Burger for lunch?
No thank you, I'd rather eat somewhere else that has bigger patties
Are you on crack?

An exclusive chain of burgers which are laced with some mysterious addictive substance as people will line up for a mile to get their ‘animal style’ fries and 4x4 burger.

They also have bible scriptures on the inside of their cups and most of the original heirs to the burger dynasty all died in very odd ways.
