To manage a food allergy at a restaurant, tell the staff early, tell the right person, and be specific: name the allergen, say it is an allergy rather than a preference, and ask how the dish is prepared as well as what is in it. Then confirm again when the food arrives. In the UK, restaurants must give you allergen information, so you are not asking a favour. The steps below set out how to have that conversation clearly, and what to do if the answers do not reassure you.
Key takeaways
- Phone ahead at a quiet time and speak to a manager or chef if you can.
- Name the allergen and say it is an allergy, so staff understand small amounts matter.
- Ask about cross-contact, such as shared fryers, not just ingredients.
- Confirm the dish is the right one before you eat, and keep your medicines and plan with you.
Why the way you tell staff matters
The NHS guide to food allergy advises checking restaurant menus carefully and telling staff at restaurants and cafés about your allergy. It sounds simple, but a message passed from you to a server, then to a kitchen at its busiest, can easily lose detail along the way. The aim is to make your information hard to misunderstand and easy to act on.
The law gives you a starting point. The UK government’s food allergy and intolerance advice for consumers says that when you eat out or order a takeaway, the restaurant or café must provide allergen information for the 14 regulated allergens. It can be written or spoken, but if it is spoken, the business must signpost where you can get it.
How to manage a food allergy at a restaurant, step by step
- Phone ahead. The children and young people’s allergy network run by NHS Scotland suggests phoning a place ahead of time and choosing a time when staff are likely to be quiet and able to talk without rushing.
- Ask for the right person. The same guidance notes that the person taking your order may not be the best person to ask, and suggests speaking to a manager or, better still, the chef.
- Use clear words. “I have a severe peanut allergy” is better than “I can’t really have nuts”. Name each allergen.
- Ask about preparation. Ask whether your food could come into contact with the allergen, for example through a deep fryer used for everything.
- Repeat it when you arrive. Staff change between a phone call and a booking. Mention it again to whoever seats you and whoever takes the order.
- Confirm at the table. When the food comes, check that this is the dish prepared for your allergy before you eat it.
What to say: a simple script
Short, structured information is easier for a busy team to pass on. You might adapt this:
| Moment | What you might say |
|---|---|
| Booking | “I have an allergy to sesame. Could I speak to someone who can check the menu with the chef?” |
| Ordering | “This is an allergy, not a preference. Does this dish contain sesame, and is anything cooked in the same oil or on the same surface?” |
| Unsure answer | “Could you check with the chef, please? I’d rather wait than guess.” |
| Food arrives | “Is this the sesame-free dish?” |
If you have several allergies or intolerances, write them down so staff can take the note to the kitchen. A clear card or note on your phone helps, especially if you are eating somewhere where you do not speak the language well.
Reading the response
A good response sounds specific: staff check, come back with clear answers, and explain how the kitchen keeps your food separate. A worrying one sounds rushed or vague. The government guidance is blunt: if you have any doubt about the staff understanding the importance of your dietary needs, do not eat there. It also notes that businesses must give allergen information but are not required to offer you an alternative meal, so a kitchen that says it cannot cater for you safely is being honest, not unhelpful.
Many of the same preparation questions apply to coeliac disease, and our checklist on gluten cross contamination goes through fryers, toasters and boards in detail. If you are newer to managing a condition when eating out, our guide to eating out with coeliac disease also covers how to raise it before you order.
Be ready in case of a reaction
Bring your medicines and your allergy action plan every time. The NHS lists signs of a severe reaction, anaphylaxis, including a throat that feels tight, difficulty swallowing, and swelling of the lips, mouth, throat or tongue. If you have an adrenaline auto-injector, the NHS says to use it immediately and call 999 for an ambulance, even if you start to feel better.
The NHS Scotland allergy network adds a practical point: if you have a reaction, follow your plan and do not go outside or to the toilet alone. Tell the people you are eating with what to do before you start, not during an emergency.
Frequently asked questions
Do I have to explain my medical history to the server?
No. Name the allergen, say it is an allergy, and say how careful the kitchen needs to be. That is all staff need to act on it.
If I have eaten somewhere safely before, can I skip the conversation?
It is better not to. The NHS Scotland guidance points out that recipes change and chefs change, so a dish that was safe last month may not be the same today.
What should I do if a restaurant gets it wrong?
Deal with any reaction first and follow your clinician’s plan. The government advice then suggests telling the food business, and you can report a business that is not meeting allergen requirements to its local authority.
Your next booking
Before your next meal out, write a two-line note naming your allergens and the questions you want answered, and save it on your phone. Use it when you call ahead and again when you order. It keeps the conversation calm and consistent, and it gives the kitchen exactly what it needs. More guides are in our Food Allergies section, and if your allergy is new or changing, your allergy clinic or GP is the best source of personal advice.
