Managing Dietary Requirements at Your Restaurant: A Staff Guide
By Reserva
The Stakes Have Raised
Managing dietary requirements in a restaurant is no longer a question of courtesy — in many cases, it's a legal obligation. The UK's 14 allergen regulations require businesses to provide accurate information about allergens in every dish, and a failure to do so can have consequences ranging from a severe customer health incident to regulatory action.
Beyond the legal dimension, the dietary landscape has changed significantly. Vegan, gluten-free, dairy-free, and low-FODMAP requirements have moved from rare requests to everyday bookings. A restaurant that handles them well — confidently, specifically, without making the customer feel like a burden — builds genuine loyalty among a customer group that is often underserved.
Building the System: From Booking to Kitchen
The most common dietary requirement failures happen not because the kitchen can't accommodate the need, but because information doesn't flow reliably from booking to front-of-house to kitchen. A customer who specified a nut allergy at booking arrives to find the team unaware.
The fix is a system, not just goodwill:
At booking: Capture dietary requirements as a mandatory optional field in the booking process. Make it specific — a text field rather than a checkbox of common requirements, since individual needs vary significantly.
At confirmation: Include the stated requirements in the booking confirmation email, so the customer can correct any misunderstanding before the visit.
In the pre-service briefing: Every booking with a dietary requirement should be flagged in the day's briefing. The relevant table and the specific requirement should be known by every member of the team before service begins.
At the table: Front-of-house staff should confirm requirements on arrival and again before ordering. A brief "I understand you have a nut allergy — I want to make sure we have that noted for your table" takes 10 seconds and builds immediate confidence.
In the kitchen: Dietary requirements should appear on kitchen display screens alongside the order, flagged prominently. The chef responsible for the dish should confirm to the relevant station that the requirement has been accommodated.
The 14 Allergens
Under UK law, you must be able to tell customers if any of the 14 major allergens are present in your dishes. These are: celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, nuts, peanuts, sesame seeds, soya, and sulphur dioxide.
This information must be available in writing — a printed allergen menu, a QR code linking to an allergen chart, or an online menu with allergen information — not just communicated verbally on request.
Handling Complex Requirements Confidently
Some customers arrive with complex, overlapping requirements. A guest who is coeliac and allergic to eggs and dairy requires careful handling across every dish. The best restaurants handle this with a specific conversation between the guest and a knowledgeable team member — not a server who has to disappear repeatedly to check with the kitchen.
Empowering at least one senior member of front-of-house per service to handle complex dietary conversations confidently — with full knowledge of your menu's ingredients — is an investment that pays dividends in customer confidence and safety.
Making It a Selling Point
Restaurants that handle dietary requirements exceptionally well often don't realise they have a genuine competitive advantage. The gluten-free diner who finds a restaurant that takes their requirement seriously, explains the menu accurately, and serves dishes that are genuinely good — rather than an afterthought — becomes a loyal advocate.
In communities — vegan communities, coeliac communities, allergy parent networks — word spreads quickly about businesses that get this right. Being the restaurant that handles dietary requirements with confidence and care is a form of positioning that attracts a specific and loyal customer segment.
