Dietary requirements: how to check a restaurant can cater for you

Eating out should be enjoyable, but if you have allergies, intolerances or specific dietary preferences, planning ahead is necessary. UK restaurants are required to provide certain information, but not every menu or website will answer your questions fully. Knowing what to check, what to ask, and how to compare options helps you book with confidence and avoid surprises at the table.

What UK law says about allergen information

Every food business in the UK is required to provide information about the 14 major allergens in the food they serve. This includes restaurants, cafés, pubs and takeaways. The law covers allergens such as peanuts, tree nuts, milk, eggs, fish, shellfish, soya, celery, mustard, sesame, sulphites, lupin, gluten-containing cereals and molluscs.

• You have the right to ask for allergen information for any item on the menu. Staff should be able to provide this, either in writing or verbally.
• Pre-packed food (such as sandwiches made on site and wrapped) must have a label with a full ingredients list and highlighted allergens.
• For restaurant dishes, there may be an allergen menu, symbols on the main menu, or a process where staff check with the kitchen. If the answer is unclear or hesitant, ask to see written information or to speak with a manager.
• The law does not cover every possible dietary requirement—only the 14 major allergens. Other needs, such as low-FODMAP, specific intolerances, or preferences, are not covered by the same rules.

While the law gives you a starting point, it is still wise to confirm details directly with the restaurant, especially if your requirements are strict or if you have previously had issues with cross-contact.

How to ask about allergens and cross-contact

Contacting the restaurant before you book is often the best way to check whether they can safely cater for you. How you ask can make a real difference to the clarity of the answer you receive.

• Phone ahead and state your requirements plainly. Say what the allergy or intolerance is, and ask whether the kitchen can cater for it rather than simply asking if something is 'safe'.
• Ask specifically about cross-contact. For example: "How do you avoid cross-contact with nuts in your kitchen?" or "Do you use separate utensils and preparation areas for gluten-free dishes?" A reassuring answer will explain steps the kitchen takes—such as separate pans, cleaning routines, or dedicated fryers. If staff cannot explain this, or seem unsure, it is reasonable to be cautious.
• Check for written allergen information. Ask if there is a written allergen menu you can review, and whether staff are trained to answer questions about allergens. If the allergen information is only available verbally, listen for detail and confidence in the reply.
• Ask who will prepare your food. In smaller places, the person taking your call may also be the chef. In larger restaurants, they may need to check with the kitchen. A careful business will not rush your enquiry.

If you are satisfied with the answers and staff seem knowledgeable, that is a good sign. If you feel rushed, dismissed, or cannot get clear information, you may wish to look elsewhere.

Comparing vegetarian, vegan, halal and gluten-free options

Restaurants may label options as vegetarian, vegan, gluten-free or halal on their menus, but these terms are not regulated by law in the same way as allergens. It is useful to compare what is offered before you book, but not every menu, website or directory will state every option.

• Menus versus comparison facts. Some restaurants publish detailed menus online, listing vegetarian, vegan or gluten-free dishes. Others only provide this information at the venue. Annuvell Local shows vegetarian and vegan comparison facts for restaurants, and vegetarian, vegan, halal and gluten-free facts for takeaways. If a fact is marked Not stated, it means the directory has no evidence either way—not that the option is unavailable.
• What to do if information is missing. If you need to be certain, check the restaurant’s listing for contact details and phone ahead. You can ask how dishes are prepared and whether alternatives are available (such as non-dairy milk or gluten-free bread).
• Ask how strict they are. Some kitchens prepare vegetarian or vegan dishes in areas where meat or dairy are also handled. For halal or gluten-free, check whether there is certification or a guarantee of separate preparation. A clear, specific answer is usually a good sign.
• Look for flexibility. Some businesses are willing to adapt dishes on request. Ask whether substitutions are possible, especially if you have multiple requirements.

Online menus and comparison facts are a useful start, but only a direct conversation with staff will confirm how strictly your requirements can be met.

Booking for groups with mixed dietary requirements

Organising a meal for a group with different needs takes extra planning. The earlier you contact the restaurant, the more likely they are to help you accommodate everyone.

• List everyone’s requirements. Before you call, write down the dietary needs for everyone in the group—whether that is nut allergy, gluten intolerance, vegetarian, vegan, halal, or other preferences.
• Ask about group bookings. Explain that your group includes people with different requirements, and ask whether the kitchen can handle them all at once. Some restaurants can adapt set menus or provide special dishes if given notice.
• Request information in advance. Ask if the restaurant can send you a copy of the allergen menu or mark up the menu for your group. This helps avoid confusion on the day.
• Check how dishes are served. If food is served buffet-style or as shared platters, ask how cross-contact is avoided. For individual orders, confirm that the kitchen can keep meals separate and label them clearly.
• Agree how to confirm orders. For large groups, the restaurant may ask you to submit choices in advance. This gives the kitchen time to prepare safely and avoids mistakes.

Clear communication makes it easier for the restaurant to cater for everyone and reduces the risk of mistakes during service.

Where directories help and where you need the restaurant’s answer

Directories like Annuvell Local are a useful starting point for comparing restaurants and takeaways in your area, especially if you are looking for places with vegetarian, vegan, halal or gluten-free options. Listing pages show contact details that have been checked, and some facts about dietary options are highlighted so you can compare side by side.

• Use comparison facts to shortlist. Vegetarian and vegan options are shown for restaurants, and vegetarian, vegan, halal and gluten-free for takeaways. If a fact is Not stated, it means there is no evidence either way—so you may need to follow up directly.
• Request more details. If you need to check something specific, such as how allergens are managed in the kitchen or whether staff are trained, use the phone number or request a quote to contact the restaurant. Only the business itself can confirm exactly how your requirements will be handled on the day.
• Expect differences between listings and reality. Menus and options change, so even if a directory or the restaurant’s own website lists certain dishes, checking directly with staff is always recommended for allergies and strict dietary needs.
• Look for verified details. Annuvell Local marks a phone number as verified only if the business has published it. This can save time if you are calling ahead about sensitive requirements.

By combining a directory search with a follow-up call, you can quickly narrow down your choices and focus on restaurants that are likely to be a good fit.
