RAG in FoodTech: Boost Restaurant Margins with AI Assistant

Przemysław Łata | 26th August 2025 | 7 min read

Restaurants in the GCC region are currently facing a unique opportunity, but also a serious challenge. The dynamic growth of the delivery market, rising customer expectations, and cost pressures mean that even a few percentage points of margin loss can determine the competitiveness of the entire business. Many owners and C-level managers recognize that traditional POS systems and analytical reports are not keeping pace with the rate of change. Data is scattered, decisions are made with delays, and inaccurate forecasts lead to waste.

In this context,  Retrieval-Augmented Generation (RAG) enters the scene - an approach that completely changes the way artificial intelligence supports the food industry. RAG allows AI to “understand” real restaurant data and make decisions based on facts, not statistical guesswork. This technology is what Railwaymen used to build AI Assistant for FoodTech - the first virtual assistant that can increase the average order value by up to 30% and reduce ingredient waste by 20%.

In this article, we will show you how RAG supports C-level managers in GCC restaurants in practice. If you are looking for a way to make decisions faster, reduce costs, and build a competitive advantage, read on.

Why traditional AI is not enough in food service?

In recent years, restaurants in the GCC region have been eager to invest in digital solutions – from POS systems and loyalty programs to delivery platforms. However, despite the growing amount of data, business decisions are still often based on fragmented reports and managers' intuition. For C-level executives, this means one thing: the risk of mistakes that directly impact margins.

3 key problems faced by traditional AI in the restaurant industry:

  • Hallucinations and inaccurate recommendations - Standard AI models rely on general data from the internet or a narrow set of historical information. As a result, they generate suggestions that look credible but in practice have no basis in the reality of your restaurant.
  • Scattered data sources - POS, payment apps, loyalty programs, delivery systems - each of these tools operates in its own “silo.” Gathering a coherent picture of the situation from them takes hours or days, which delays decisions and often makes them late for the market.
  • Promotions with no real impact on business - Discount and cross-sell campaigns are often launched based on intuition rather than hard data on margins and customer behavior. The result? You spend your marketing budget, but you don't see an increase in order value or improved profitability.

For C-level executives, it's a simple calculation: losing even 5-10% of margin due to poor decisions means hundreds of thousands of dollars a year. Traditional AI does not solve this problem because it relies on overly general data. You need a solution that can draw on your real data in real time and propose actions that are certain, not hypothetical.

RAG - the foundation of reliable AI for restaurants

C-level managers are well aware that data is the greatest asset of restaurants today. The problem is that traditional AI and analytical systems often cannot keep up with the dynamics of the market - forecasts based solely on historical data are not sufficient to effectively manage costs, promotions, or inventory.

This is where RAG (Retrieval-Augmented Generation) comes in - a technology that ensures that artificial intelligence no longer operates in isolation from reality, but bases its recommendations on current, verified data from your restaurant.

How does it work in practice?
Instead of generating responses based solely on the “statistical knowledge” of a language model, RAG retrieves data directly from your systems (POS, eWallet, delivery, loyalty), analyzes it, and generates precise recommendations based on that analysis.

Example: instead of receiving a general suggestion to “promote desserts,” a manager can ask the AI in simple language:

“Which dessert had the highest margin this month?”

and get a specific answer + data visualization in a second.

Why is this a revolution for FoodTech?

  • Credibility: every AI response is based on real data, not “guesswork.”
  • Real-time decisions: C-level executives don't have to wait for weekly reports - answers are available immediately.
  • Full utilization of existing systems: RAG does not replace POS or eWallet, but combines their data and makes them a real strategic tool.

For management, this means one thing: you can finally make business decisions based on facts, not intuition.

RAG in foodservice

How does RAG Assistant from Railwaymen solve key restaurant problems?

The AI Assistant for food service is not a concept from a laboratory or a “vision of the future.” It is a real solution that Railwaymen is developing specifically for restaurateurs. Thanks to the combination of RAG technology and in-depth knowledge of the catering industry, RAG Assistant was created – a virtual advisor that supports C-level staff every day in making faster, more accurate, and more profitable decisions.

Demand forecasting and loss reduction

Problem: Inaccurate forecasts lead to wasted ingredients or lost sales.

How RAG Assistant works: Our system analyzes sales history, weather, and seasonality (e.g., Ramadan, weekends) and generates purchasing recommendations. This allows managers to order exactly what they really need.

Effect: Reduction of ingredient losses by up to 20% – confirmed in real-world implementations by Railwaymen customers.

Smart promotions and upselling

Problem: Promotions without data analysis often lower margins instead of increasing them.

How RAG Assistant works: AI identifies the products with the highest margins, analyzes customer behavior, and automatically suggests promotions that really increase sales.

Effect: The average order value increases by up to 30%, which translates into a measurable increase in revenue.

Real-time decisions

Problem: Manually prepared reports are too slow, and the competition reacts faster.

How RAG Assistant works: A C-level manager asks in natural language, “Which outlet in Dubai had the highest margin this week?” and in a second gets an answer in the form of a clear chart.

Effect: Decision-making time reduced by 35% - confirmed in practice by restaurants that have implemented RAG Assistant.

Process automation

Problem: Implementing promotions or changing menus across multiple systems takes time and staff effort.

How RAG Assistant works: Once approved by the manager, the system automatically updates the POS, integrates promotions with delivery apps, and notifies the team.

Effect: Strategic decisions are implemented immediately, without delays or manual errors.

Railwaymen looks beyond FoodTech

Although we are currently focusing on GCC restaurants, the RAG Assistant architecture has the potential to support other industries as well, from fintech and retail to construction. Wherever quick decisions and data-driven work are important, this solution can become a competitive advantage.

From demo to real results - what can your restaurant gain?

Railwaymen has been working with the largest food brands in the GCC for years - Shawarmer, Alamar Foods or Wister. From conversations with owners and managers, the concept of RAG Assistant was born, which we are presenting today in the form of a demo.

Although we are in the pilot phase, it is already clear that the technology has the potential to change the way decisions are made in GCC restaurants.

What does our demo show?

  • +30% average order value (AOV) thanks to smart promotions and sales recommendations.
  • -20% ingredient waste thanks to data-driven forecasting.
  • 35% faster operational decisions thanks to natural language queries.


Industry voice


During workshops with restaurant managers at GCC, we heard a statement that best sums up the potential of RAG Assistant:

“The biggest challenge is not the lack of data, but the lack of time to analyze it. If AI does it for us, we will not only gain money, but also peace of mind.”

Railwaymen as a transformation partner
