Money & numbers
Restaurant Code
Ten mistakes that cost restaurants money — and the system that stops them.
Plate cost, waste, stock, staffing, consistency, daily numbers, selling on the floor, visibility, cash reserve and the owner’s own week — each mistake with the number that shows it, the form that fixes it and a worked example from Acacia, a restaurant we made up so the arithmetic can be shown in full. The 2026 edition adds a monthly P&L after every chapter, a self-assessment and a 10-week plan.
Every package: fill-in forms and two Excel tools. Master adds 10 workbooks, Word templates, 28 AI prompts and 13 video guides; Empire adds team manuals and the wall pack

The AI Ecosystem
QR menu, allergen matrix, POS and KDS as one system — a source for every rule, an owner for every datum and a human for every critical decision.
Book 3 of the Menu Trilogy. The allergen matrix as live data, recipe versions, cross-contact on the line, the QR menu as a digital host, one order id from table to kitchen to report, delivery platforms as channels, what AI may propose and what it may never decide, vendor contracts with a data exit — and a daily, weekly and monthly review. Every claim labelled by its source: EU, US, standard, practice, the author’s proposal or the example. One restaurant, Acacia, before and after.

People & service
The Staff Operations Manual
How we work here — a 30-day onboarding plan for a new hire, from the first day to closing the shift.
Fifteen chapters, 33 procedures and 28 forms for the kitchen, the dining room, the bar and safety — written as the first thirty days of a new hire at Acacia, a restaurant we made up so every rule can be shown being used. Each rule is marked EU, USA or good practice, with the section number and the source; where a rule is set by each state, the book says so instead of inventing one. Temperatures in °C with °F. Appendices A–E hold the allergen matrix, the handover sheet, the cleaning plan, the first-aid check and the thirty-day review.
Printable and fillable forms (A4 and Letter), seven Excel tools, wall posters, Word versions, AI prompts and video guides.

Recipes & the grill
Tastes of Power
The secret tables of world leaders through history: 36 tables, 37 recipes, and what the archives actually record.
From Jefferson’s macaroni and Lincoln’s oyster stew at the 1865 inaugural ball to the hot dog Roosevelt served a king, the Peking duck at Zhou Enlai’s banquet for Nixon, the cold noodles carried to Panmunjom in 2018 and the umngqusho Mandela’s cook of 22 years made for him. Thirty-six leaders in four chapters, each dish with servings, ingredients, numbered steps and a note on cooking it today. The book also says what it cannot prove: 18 dishes have a written record, 16 have no documented link to the leader and say so on the page, and 2 stand on a printed menu card with no evidence the leader ate them. All 87 sources are listed at the back.
One product: 37 recipes, servings on every recipe, a clickable table of contents and 87 sources grouped by chapter.

The library grows
Around 30 titles are planned, in six areas. New books appear in this shop first.
What these books are not
- They are not legal or tax advice. They point at the rule; whether it applies to your business is a question for someone qualified in your country.
- The restaurant in the examples, Acacia, does not exist. Its numbers show the method; they do not promise a result.
Who writes them
Srđan Mihailović has spent more than thirty years in hospitality — top hotel kitchens, restaurants and cruise ships, on four continents — on both sides of the business: at the stove and at the owner’s desk. He founded Gostino to put that experience into tools and books.
