One restaurant, five problems, five solutions. SOLID Principles explained through Marco's Kitchen in Carroll Gardens, Brooklyn.

Not every object lives on its own island — some know each other, some hold each other, some can't survive without each other. Five relationships, one story.

Ray says one thing every morning: let's get to work. The sewers sew, the cutters cut, the packers pack. One command, fifty different jobs. That's Polymorphism.

Dr. Frank Miller trained two residents at Mount Sinai. One became a cardiologist, the other a surgeon. Both took everything he taught them and built on top. That's Inheritance — explained through a story.
