Prerequisites

Short version: none. If you have eaten in restaurants, you can start on page one.

That is not a marketing claim, it is a design constraint. This book was written because the people who most need it — cooks who can cook, managers who can run a room, career-changers with a concept and some savings — are routinely handed material that assumes a business degree they do not have. So everything is built from the ground up.

What you genuinely need

Arithmetic. You need to be comfortable with percentages, division, and multiplication. If you can work out that \$8.52 divided by \$29.00 is 29.4%, and that 29.4% means twenty-nine cents of every dollar, you have all the mathematics this book requires. There is no algebra beyond rearranging a simple formula, no statistics, and no calculus. Where a formula appears, it is always accompanied by a worked example in dollars and a sentence explaining what it means.

A calculator or a spreadsheet. Any spreadsheet — Excel, Google Sheets, LibreOffice, Numbers. You will not be asked to write a program; there is no code in this book. You will be asked to build cost cards, schedules, and simple financial models, and a spreadsheet is the tool for that. Appendix F gives you twelve worksheet layouts with their formulas spelled out.

Willingness to do the arithmetic yourself. This is the real prerequisite. The difference between someone who has read about food costing and someone who can control food cost is entirely in the doing.

What you do NOT need

  • A culinary background. Cooking technique is not taught here and is not assumed. When the book discusses a dish, it discusses what it costs, how long it takes, and what station it lives on.
  • A business or accounting background. Chapter 31 builds the profit-and-loss statement from scratch, using only ideas the previous thirty chapters have already established. If you have never seen a P&L, you are the reader it was written for.
  • Management experience. Part IV teaches hiring, training, scheduling, and leadership assuming you have done none of them.
  • Money, yet. You do not need capital to work through this book. You need capital to open a restaurant, and Chapter 5 is about where it comes from and what it costs you.
  • Any particular software. The book names common categories of restaurant software — point of sale, inventory, scheduling, reservations — and teaches you how to evaluate them. It does not require you to have any of them, and it is not a manual for a specific product.

Helpful, but not required

  • Time on a floor or a line. Any of it — a summer bussing tables, six months on garde manger, a year behind a bar. Not because the book assumes it, but because everything in Parts III, IV, and V will land harder if you have felt a Friday rush from the inside. If you have not, the book will describe those shifts in enough detail to reason about them.
  • A restaurant you can observe. If you currently work in one, you have a laboratory. Count something. Watch the host stand for an hour on a Saturday. Ask to see a P&L. Ask what the food cost ran last month and then ask how they know.
  • A concept of your own. The progressive project works whether you use the book's fictional restaurant or substitute your own idea. If you have one, use it — Appendix C is built for that.

A note on jurisdiction

This book uses American regulatory framing: the FDA Food Code for food safety, the Fair Labor Standards Act for wage and hour, the SBA loan programs for financing, and American lease and licensing practice. The structure of the problems is universal — every jurisdiction regulates food temperature, employment, alcohol, and premises — but the specifics are not.

Wherever the law governs, the book flags it with a ⚖️ Code and Compliance callout and tells you to verify locally. That is not a disclaimer reflex. Health codes are county-level in much of the United States. The tip credit is legal in some states and does not exist in others. Liquor licenses are quota-limited and resold at auction in some cities and available on application in others. Anything consequential must be checked where you actually operate, with a professional.
