A guest with a dairy allergy sits down and opens your menu. They have two options: flag every dish they're interested in and ask your server about ingredients, or find a restaurant where the menu tells them what they need to know upfront.
More and more, guests are choosing the second option.
Dietary labels — vegan, vegetarian, gluten-free, and allergen indicators — have become a basic expectation at a growing number of restaurants. Not because of regulation (though that's coming in many places), but because guests have made it clear they want this information.
If you're also looking at the regulatory side, our guide on allergen labeling on restaurant menus covers what the new rules mean. This guide covers how to add dietary labels without cluttering your menu, what symbols and language work best, and why digital menus make this significantly easier.
The four label categories worth using
1. Vegan (V or 🌱)
A dish contains no animal products: no meat, poultry, seafood, dairy, eggs, or honey. Be precise here — "vegan-friendly" or "can be made vegan" is different from "vegan," and guests who need this distinction will notice.
2. Vegetarian (VG or V+)
No meat, poultry, or seafood. May contain dairy and eggs. The distinction from vegan matters — a cheese pizza is vegetarian, not vegan. Use separate symbols for each.
Note on symbols: There's no universal standard, but V for vegan and VG for vegetarian is a common convention, though some restaurants reverse this. Whatever you choose, define it clearly in a key at the bottom of the menu.
3. Gluten-free (GF)
The dish contains no gluten-containing ingredients. If cross-contamination is a risk in your kitchen (shared fryers, prep surfaces, or utensils), note this. Many guests asking about gluten-free options have coeliac disease, not just a preference — "contains no gluten ingredients but prepared in a kitchen that handles gluten" is honest and important information.
4. Allergen indicators
The Big 9 allergens recognised in the US (and similar lists in the EU and UK) are: milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybean, and sesame.
You don't need to list every allergen on every dish — this creates visual noise and isn't how most menus work. A practical approach: mark dishes that are free from the most commonly requested allergens (nut-free, dairy-free, shellfish-free), and note in your menu footer that guests can ask about specific allergens for any dish.
How to display labels without cluttering the menu
The most common mistake is adding so many labels that the menu becomes hard to read. A dish with five icons next to it starts to look like a warning sign rather than an appealing option.
Keep icons small and consistent. A two-letter abbreviation (V, VG, GF) next to the dish name is enough. You don't need coloured badges, leaf icons, and text all at once.
Define your symbols once, clearly. A small key at the bottom of the menu page (or in a header): "V = vegan, VG = vegetarian, GF = gluten-free." This way the symbols stay minimal and guests understand them.
Be accurate over being comprehensive. Only label what you're confident about. A dish labelled "vegan" that turns out to contain butter is worse than no label at all. Good menu descriptions help set expectations clearly. When in doubt, leave it unlabelled and let staff answer the question.
Separate dietary preference from allergy. Some restaurants use different visual treatments — for example, a simple V for vegan (preference) and a highlighted GF for gluten-free (potential health issue). This helps guests who are scanning for safety reasons versus preference reasons. Understanding menu psychology can help you decide how prominently to display these labels to influence choice positively.
Why digital menus handle this better
On a printed menu, every change to allergen information requires a reprint. If you modify a recipe — a new sauce, a different garnish, a supplier change — and the allergen content changes, guests are still reading the old information.
On a digital menu, you update the label and it's live immediately. No lag, no outdated menus circulating the dining room.
Digital menus also give you more space per dish. Instead of squeezing a list of allergens into a small printed box, you can expand each dish to show detailed information: full ingredient list, preparation notes, allergen breakdown. Guests who need this information can tap to see it. Guests who don't need it see a clean menu.
This is particularly useful for the distinction between "contains no allergen" and "may contain traces due to kitchen processes." A note like this fits naturally as expandable detail on a digital menu, but takes up valuable real estate on a printed one.
What's coming in terms of regulation
In the US, allergen labelling requirements for restaurants are evolving. California's ADDE Act — partially in effect since October 2025, with further requirements from July 2026 — requires clearer allergen disclosure on menus. Other states are watching.
The EU already requires restaurants to disclose 14 major allergens for dishes on their menus. The UK has similar requirements post-Brexit.
If you're not labelling allergens yet and you're in a regulated jurisdiction, check your local requirements. The cost of getting ahead of this is low — a few hours to label your menu accurately. The cost of a guest reaction attributable to unclear labelling is much higher.
A practical starting point
If you're adding dietary labels for the first time:
- Go through your menu dish by dish with your chef
- Mark everything that is definitively vegan, vegetarian, or gluten-free (not "can be adapted")
- Note any dishes that are free from the most commonly requested allergens
- Add a clear key to your menu
- Train your front-of-house staff so they can answer follow-up questions confidently
Start with what you're certain about. Add more labels as you verify them. A menu with accurate labels on 30% of dishes is better than one with uncertain labels on 100%.
Guests who need this information will find your restaurant easier to navigate. Guests who don't need it will barely notice the small symbols. It's one of those changes that has almost no downside and a meaningful upside for a specific group of guests who will remember which restaurants make it easy for them.
