What we do

Full-service food consulting: from concept to profitability

A food consultant is not someone who tells you what to put on the menu. It is a professional who analyzes your hospitality business in its entirety — finances, operations, team, marketing, concept — and identifies exactly where money is being lost and how to recover it. At ChefBusiness, our food consulting is based on real data from the Spanish market and over 29 years of direct experience in the sector.

We work with independent restaurants, restaurant groups, bars, cafes, hotel F&B departments, dark kitchens, catering companies, and international investors entering the Spanish market. Every format has its own rules — and we know them all.

FAQ

Frequently asked questions about food consulting

What does a food consultant do?
A food consultant analyzes and improves every aspect of a hospitality business: financial viability, daily operations, menu design, team management, marketing, and brand positioning. Unlike a chef consultant who only works on the kitchen, a professional food consultant addresses the business holistically — from the numbers to the plate.
How much does food consulting cost in Madrid?
At ChefBusiness, food consulting starts with a Gastronomic Diagnosis from EUR 1,250. Monthly mentoring from EUR 450/month. Full consulting projects (opening, restructuring, business plan) from EUR 2,500. Prices vary by project complexity and do not include VAT.
Do you work with international clients and restaurant chains?
Yes. We work with international investors, restaurant groups, and entrepreneurs opening in Madrid and Barcelona. Chef John Guerrero speaks English and Spanish and has direct experience with Latin American, European, and North American clients entering the Spanish market. We handle visa coordination, company formation, and cross-cultural adaptation.
What types of food businesses do you consult for?
We consult for all hospitality formats: independent restaurants, hotel F&B departments, bars and tapas bars, cafes, dark kitchens, catering companies, bakeries, and restaurant groups. Each format has its own operational dynamics and we apply specialized methodology accordingly.
Can you help open a restaurant in Spain from abroad?
Absolutely. We offer end-to-end consulting for international investors: concept validation in the Spanish market, business plan with financial model, entrepreneur visa coordination, Spanish company formation (SL), location search, licensing, team recruitment, and launch strategy. We start remotely and you travel to Madrid only for key phases. Typical timeline: 4-9 months.
What results can I expect from food consulting?
Our clients achieve an average profitability increase from 6% to 18% after consulting engagement. Food cost reductions of 3-7 percentage points are typical. For new openings, our methodology achieves a 90%+ survival rate beyond year one — compared to the industry average of 40%.
How is ChefBusiness different from other food consultants?
Chef John Guerrero combines 29+ years of hands-on hospitality experience with data-driven business strategy. We are not a management firm that reads spreadsheets — we understand kitchens, operations, and the realities of Spanish hospitality from the inside. We also offer 16 free digital tools for restaurant management and a proprietary diagnostic methodology.
Do you offer remote food consulting?
Yes. We offer in-person consulting in Madrid and remote consulting for all of Spain (Barcelona, Valencia, Seville, Malaga) and Latin America. Our remote service maintains the same methodology and depth as in-person. Key milestones may require on-site visits depending on the project.
