Does this have nuts? Is the broth halal?_ A QR menu with allergen filters turns that question into a tap — and turns anxious guests into confident, repeat customers. This guide shows you exactly how to set up **QR menu allergen filters** for halal, vegan, gluten-free and the top eight allergens, so diners see safe options in seconds. If you have already launched your digital menu (see our [quick-launch guide for New Cairo restaurants](/blog/how-to-launch-a-qr-menu-in-a-new-cairo-restaurant-in-under-4)), this is the single highest-impact feature to add next. Allergen visibility is not a nice-to-have — in 2026 it is a legal expectation, a trust signal, and a direct driver of table turnover. ## Why Allergen Visibility Matters for Restaurants A paper menu cannot filter itself. When a guest with a shellfish allergy or a vegan diner sits down, they are forced to interrogate the menu line by line, flag down staff, and trust a waiter's memory of every ingredient. That friction has real costs: - **1 in 3** diners globally report a food allergy or dietary restriction that affects ordering. - **Hospital admissions** for anaphylaxis have risen sharply over the past decade, making allergen disclosure a liability concern, not just hospitality. - **67% of diners** say they are more likely to return to a restaurant that clearly labels dietary information. For MENA restaurants specifically, halal certification is the baseline — but within that, guests increasingly ask about **vegetarian, vegan, gluten-free, dairy-free, and nut-free** options. Tourist hubs in Sharm el-Sheikh and Hurghada face an even broader mix: international guests arrive with keto, paleo, halal, and allergen requirements all at once. When a menu simply says "may contain traces" on everything, anxious diners order the safest, cheapest item — or leave. Precise, per-item filters let them order confidently and spend more. A digital QR menu solves this at the source. Each dish carries its own allergen and dietary tags, and a guest can toggle a filter to instantly see only the items that match their needs. No guesswork, no waiter interrogation, no liability gap. For restaurants that also run [modifiers and add-ons](/blog/qr-menu-modifiers-sizes-add-ons-toppings-explained), combining those with allergen tags lets guests customize safely — "make it vegan, no cheese, extra hummus." ## The Dietary & Allergen Tags That Matter Most Before you configure anything, decide which tags your menu actually needs. Over-tagging clutters the interface; under-tagging defeats the purpose. Here is a practical set tailored to Egyptian and Red Sea restaurants: ### Dietary Lifestyle Tags - **Halal** — the default for most Egyptian menus, but worth confirming and labeling explicitly for tourists. - **Vegetarian** — no meat or fish; may include dairy and eggs. - **Vegan** — fully plant-based, no animal products. - **Pescatarian** — fish and seafood only, no meat. - **Keto / Low-carb** — useful for health-conscious diners. ### Allergen Tags (The Top 8) - **Gluten** — for celiac and gluten-sensitive guests. - **Nuts** — peanuts and tree nuts. - **Dairy** — lactose intolerance is common in the region. - **Shellfish** — a major anaphylaxis risk. - **Egg** — frequently hidden in sauces and desserts. - **Soy** — common in marinades and processed items. - **Sesame** — widely used in Middle Eastern cuisine (tahini). - **Mustard** — present in many dressings. Notice that **sesame** is on the list. It is one of the most common allergens in the Middle East precisely because tahini, sesame oil, and sesame seeds are everywhere. Many generic Western allergen tools omit it — a MENA-native platform gets this right by default. ## Step-by-Step: Setting Up Allergen Filters in Menyo Pro The setup follows three phases: create your tag library, apply tags to each dish, and enable the guest-facing filter toggle. You can do all of this from the menu editor without writing any code. - A live Menyo Pro menu (if not, follow the [QR code menu setup guide](/blog/how-to-set-up-qr-code-menu) first). - A complete ingredient list for every dish — ask your head chef. - 15–30 minutes for a typical 40-item menu. ### Step 1 — Build your tag library Open the menu editor and navigate to **Settings → Dietary & Allergen Tags**. Here you define the set of tags that will appear across your menu. Start with the essentials listed above. You can rename tags, choose icons, and set a color for each — green for lifestyle tags (halal, vegan), red for warning allergens (nuts, shellfish). Consistent colors help diners scan quickly. Green tags read as permission; red tags read as caution. Use this psychology deliberately — a guest who sees a row of green "vegan" badges feels invited to order, not warned away. ### Step 2 — Tag each dish accurately For every item in your menu, open its edit panel and toggle the relevant tags. This is the most important step, and accuracy is non-negotiable. A mislabeled allergen is a health risk, not a typo. Tag systematically by category: - **Appetizers (mezze):** hummus is vegan and gluten-free; baba ghanoush is vegan; vine leaves are vegan — but check if they contain rice (gluten-safe) or ground meat. - **Main courses:** tag grilled meats as halal; flag any dish breaded or fried in shared oil as containing gluten. - **Desserts:** konafa and baklava almost always contain gluten, dairy, and nuts — tag all three. - **Beverages:** fresh juices are vegan; milk-based drinks carry dairy. If your kitchen fries breaded chicken in the same oil as fries, the fries are not truly gluten-free. Add a "made in a kitchen that handles X" note where relevant. Honesty here protects guests and protects you. ### Step 3 — Enable the guest-facing filter In **Settings → Menu Display**, turn on **Dietary Filters**. This adds a row of toggle buttons at the top of your live menu: a guest taps "vegan" and the menu instantly hides non-vegan items. The toggle is additive — a guest can combine "vegan" + "gluten-free" to see only dishes that satisfy both. This is the feature that changes behavior. Instead of reading every description, a vegan guest sees exactly five matching dishes in one tap. That is the difference between a frustrated guest and a confident order. ## Designing Your Menu Around Dietary Filters Filters work best when your menu is structured to support them. A few design principles make the experience dramatically smoother for guests and staff alike. Resist the temptation to create separate "Vegan Menu" and "Regular Menu" sections. That fragments your menu and confuses guests who want to see everything. Instead, keep dishes grouped logically (appetizers, grills, desserts) and let the filters do the work. One menu, infinite views. Pair this with strong visual [customization](/blog/how-to-customize-qr-menu-colors-logo-photos). Each tag should carry a small icon and a color band so it is legible at a glance — your 80-year-old grandmother and a backpacking tourist should both understand the green leaf means vegan. For restaurants serving international guests, this pairs naturally with a [multilingual menu](/blog/setting-up-multilingual-qr-menus-for-red-sea-and-sinai-resor): the allergen icons are language-independent, so they communicate even when the guest does not read Arabic or English fluently. ## The Real-World Payoff Restaurants that implement allergen filters report three measurable changes, usually within the first month. - **Fewer interruptions:** waiters spend dramatically less time answering "is this vegan?" — the menu answers it. - **Higher average ticket:** confident diners order more. An anxious diner orders one safe item; a confident one orders a starter, main, and dessert. - **Better reviews:** "finally a restaurant that clearly labels allergens" is the kind of Google review that brings in the next dietary-conscious party. For full-service restaurants where labor cost is the dominant expense, cutting repetitive allergen questions is a direct operational saving — part of the broader [labor cost case for QR menus](/blog/the-labor-cost-case-for-qr-menus-in-egyptian-full-service-re). Every minute a waiter spends reciting ingredients is a minute not spent serving the next table. ## Common Mistakes to Avoid **Tagging from memory instead of recipes.** Your chef knows the food, but human memory misses the sesame oil in the marinade or the egg wash on the pastry. Pull the actual recipe for each dish and tag from that. Audit once, trust the result. **Never updating tags after a recipe change.** If you swap a sauce or add a new garnish, the allergen profile may change. Build a rule: any menu change triggers a tag review for the affected dish. **Overusing the "may contain" disclaimer.** If every item says "may contain nuts," the tag is meaningless and anxious guests will not trust any of it. Reserve cross-contamination warnings for genuine shared-equipment situations. ## Frequently Asked Questions **Do allergen filters work offline?** Yes — once a guest has opened the menu, the filter toggles work even if the connection drops, because the dish data is already loaded on their phone. This matters for restaurants with spotty Wi-Fi in garden or rooftop seating areas. **Can I show allergen icons without a filter toggle?** Yes. If you prefer a simpler menu, you can display tags as badges on each dish without the interactive filter row. The filters are an optional layer on top of the always-visible badges. **How do I handle custom or off-menu requests?** The filters cover your standard menu. For off-menu modifications, train staff to consult the same tag library so their verbal answers match what the digital menu would show. Consistency is what builds guest trust. **Is halal a dietary tag or an allergen?** Halal is a dietary lifestyle tag, not an allergen. Keep the two categories separate in your tag library — this keeps the interface clean and lets guests combine them (e.g., "halal" + "gluten-free") without confusion. ## Start With the Dishes That Matter Most You do not need to tag all forty dishes in one sitting. Start with the dishes that generate the most allergen questions — usually the mezze platter, the mixed grill, and the desserts. Tag those first, enable the filter, and you have already solved the majority of guest anxiety. Expand to the full menu over the following week. Allergen and dietary filters are one of the few menu features that are simultaneously a safety measure, a trust signal, and a revenue lever. They protect your guests, reduce your staff's workload, and increase your average ticket. If you are designing a menu from scratch, build this in from day one alongside your [high-conversion menu design](/blog/designing-high-converting-digital-menus-for-new-cairo-fine-d) — it is far easier than retrofitting it later. The restaurants that win the next wave of diners are not the ones with the flashiest menus. They are the ones where a guest with a dietary need can sit down, tap twice, and feel completely safe ordering. That is what QR menu allergen filters deliver. --- *Published on 2026-07-12 by Menyo Team.
