The Menu Trilogy

Three books. One menu that works for you.

The trilogy takes a menu from a plain price list to a smart tool for making money. The first book explains how guests choose, the second what each dish is really worth, the third how software runs it all for you. Each book also stands on its own.

2 · The numbers decideCost, margin, recipe specs, stock
3 · Software runs itQR menu, allergens, till and kitchen
Book 1AVAILABLE
Cover of The Choice Algorithm

The Choice Algorithm

Menu psychology and architecture. Menu engineering, price psychology, the decoy effect and menu layout — with an evidence grade for every piece of advice.

Book 2AVAILABLE
Cover of The Code Equation

The Code Equation

Menu maths: food cost, recipe specifications, pricing and stock — and exactly where the money goes. Costing to the cent, yield, purchasing, pricing with VAT, drinks, stock and the monthly reconciliation.

Book 3AVAILABLE
Cover of The AI Ecosystem

The AI Ecosystem

The menu in the digital world: QR menu, allergen matrix, till and kitchen screen as one system — with one source of truth, one order id and a human for every critical decision.

What makes it different

Every claim with its evidence grade.

Menus attract plenty of talk and very little measurement. Till-system blogs and consultants still copy figures from studies that don’t hold up. The Choice Algorithm says, for every claim, how well it has really been measured, and gives the source — and where there is no evidence, it says so.

Book 1 · contents

Ten chapters. Ten numbers to track.

Three parts: how guests choose, the architecture of the offer, and drinks plus testing in your own dining room. Every chapter has a number you measure, forms, one restaurant worked through with every figure, and the rules for the EU, the UK, the US and Serbia where they differ.

Look inside

One restaurant, every number.

The full menu of Acacia, a fictional restaurant — dishes, prices, costs, sales and labour minutes — runs through the book from the first page to the last. After every chapter the P&L shows what the change brought: from €408 profit before tax a month at the start to €1,538 at the end, from menu changes alone. The assumptions are deliberately more modest than what the research measures.

For people who build menus. Not for people looking for tricks.

This book is for you if

  • you run a restaurant, bistro, tavern, bar or hotel restaurant and decide the menu yourself
  • you are a head chef or manager responsible for prices and sales
  • you are preparing a new menu and want to build it on evidence, not on gut feeling
  • you are a designer or consultant who creates menus for hospitality businesses

This book is not for you if

  • you want tricks that get guests to pay for things they didn’t want
  • you are looking for recipes or cooking techniques
  • you are not prepared to measure a change before calling it a success

Questions

Before you choose

What format is the book?

A 191-page PDF, 2026 edition. It reads on a phone, tablet or computer. The printable forms are A4; the fill-in forms for the computer come in A4 and US Letter.

What language is it in?

British English. There is also a Serbian edition, Algoritam izbora.

Are Book 2 and Book 3 out?

Yes. Book 2, The Code Equation: menu maths — food cost, standard recipes, pricing and stock. Book 3, The AI Ecosystem: QR menu, allergen matrix, POS and KDS as one system.

How does the trilogy set work?

Each book costs €39; all three together cost €99. All three books are out. If you have already bought one or two, you pay only the difference up to €99.

What comes with the book?

Everything: forms to print and to fill in, the Excel workbooks and the Acacia workbook, Word templates, AI prompts, the menu audit kit, wall posters and video guides. No tiers and nothing extra to pay.

Do I need to read Restaurant Code first?

No. The Choice Algorithm stands on its own. If you have Restaurant Code, you will recognise Acacia: the same restaurant and the same starting point, but this book goes much deeper into the menu.

What does the evidence grade mean?

Every claim says how well it has been measured: strong, moderate, weak, myth, unreliable or not verified. The grade belongs to the claim, not to its author, and it is the same throughout the book; a table of every claim is in the appendix.

Are the examples from a real restaurant?

No. Acacia is a fictional restaurant, the same one from the first page to the last. Its numbers show the method; they don’t promise a result. Every fact from research has a source at the end of its chapter.

How do I get the book after I buy it?

Checkout is through Gumroad. Once you pay, the download link arrives in your inbox right away.

One change to the menu. Four weeks of measuring.

Then a decision based on the numbers, not on gut feeling.
