SushiDog uses Served Source to manage allergens, ingredients and nutrition across its 18 UK sites. Served Source is part of Served (served-app.com), the London-based allergen management platform. It works at ingredient level: it reads SushiDog’s supplier spec sheets, flags allergens and “may contain” statements for the team to check, and builds each dish’s allergen and nutrition information. Change one ingredient, and every dish that uses it updates. Ambra Barbera, SushiDog’s Food & Quality Manager, says the allergen side of their latest menu launch went “more smoothly than ever”.

SushiDog's Food & Quality Manager, Ambra Barbera, used to find updating allergen and nutrition information incredibly frustrating. Since moving to Served Source, her team can now manage the entire process easily, from checking supplier spec sheets to launching special menus.

"Allergen and nutrition management used to be one of the most stressful parts of my job… Moving to Served has been a game changer."

Who is SushiDog?

SushiDog is a quick-service chain with 18 sites across the UK, the latest of which opened in Wimbledon on 30 October 2026. It specialises in fresh, affordable grab-and-go SushiDogs, sushi bowls and salads, built at the counter and completely customisable.

How did Served and SushiDog meet?

The relationship between Served and SushiDog started with a name badge. In Served's early days, co-founder Alana Bralsford was at a conference when she glanced at the badge of the person next to her. She read "SushiDog" and "Head of Marketing", and she immediately introduced herself.

That led to an informal drink and some incredible early advice. A few months later, SushiDog hired Ambra Barbera as Food & Quality Manager. She needed better allergen software, and SushiDog's marketing lead introduced her to Served. SushiDog launched with Served Core across its UK sites, and has now moved to Served Source.

What was the problem with managing allergens before Served?

Before Served, SushiDog managed allergens through a manual process. When allergen information changed, the team had to update every dish containing that item by hand, in software they found hard to use.

Ambra describes the previous system as "so difficult to use that it genuinely brought me to tears with frustration".

Allergen management software has to be simple to use, because allergen information is only as accurate as its last update. New supplier products, recipe tweaks and limited-edition dishes can happen very quickly and all need accurate, comprehensive and immediate changes.

Why did SushiDog move from Served Core to Served Source?

SushiDog first launched with Served Core, Served’s standard product: live allergen menus for guests, plus the Served Hub, where the team manages menu data and sees analytics on how guests use the menus. When a recipe changed, the team updated it in the Served Hub, and SushiDog’s guest-facing menus updated straight away. Guests could open those menus on the EAT map by Served, on SushiDog’s website before they arrived, or in store using a QR code.

Served Source goes a level deeper, to individual ingredients. If a supplier’s soy sauce arrives with a new “may contain”, the team updates the soy sauce once in the Served Hub, and every dish that uses it updates too.

Served Source also reads ingredient information from supplier spec sheets and calculates nutrition and calories, which restaurants can then show guests on their live allergen menus.

How does Served Source work for SushiDog?

Served Source takes the data from SushiDog's supplier spec sheets, flags allergens and "may contain" statements, and builds each dish's allergen, ingredient and nutrition information from them.

  1. Spec sheets come in. SushiDog’s team uploads supplier spec sheets to Served Source.
  2. Served Source reads them, and a SushiDog team member checks alongside. Served Source uses AI to scan each spec sheet and shows the results side by side with the original, so the person reviewing it can check every detail. It's there to support human checking, not replace it. It flags "may contain" statements and highlights any changes or discrepancies so the team has full visibility.
  3. Dishes are built from products. Every dish is built from its ingredients, component by component. Served Source calculates calories, macros and high fat, salt and sugar (HFSS) scores for each dish. For every allergen on a dish, the back-of-house view shows which component it comes from.
  4. The team checks and publishes. SushiDog's team can see and check all the information in the Served Hub before it goes live on the guest menu.
  5. Changes flow through. When an ingredient changes, the team swaps it once, and Served Source recalculates the ingredient list, allergens and nutrition for every dish that uses it, or only the dishes the team chooses. When SushiDog replaced its nut-based sauce with a nut-free sunflower satay from SUNFLY, one swap updated every relevant dish.

What does a guest see?

SushiDog guests can view the allergen menu on the EAT map by Served, on SushiDog’s website before they arrived, or in store using a QR code. Guests filter the menu by their allergies to see which allergens each dish “contains” and which it “may contain”. They can then talk to staff, who see the same live information, so the conversation is transparent and informed.

There are four ways to find SushiDog's allergen menu:

  1. The EAT map: find your nearest SushiDog, check the menu and head straight there.
  2. In store: scan the QR code on the counter.
  3. The SushiDog app: tap "You" in the bottom right, scroll down to Support, then tap "Allergens".
  4. SushiDog's website: follow the allergen menu link [link].

Always tell staff about your allergy before you order. The allergen menu shows the restaurant's recorded allergen information. It does not confirm that a dish is safe for you.

What has changed for Ambra's team?

Ambra says the allergen side of their latest menu launch "went more smoothly than ever", and that front-of-house teams report quicker conversations with guests.

"Getting all our ingredient, nutrition and calorie data onto Served Source was seamless, and the help we had from the team for our latest menu launch meant the allergen side went more smoothly than ever. Our front-of-house teams tell us it's speeding up guest conversations on site, and the feedback from guests has been amazing."
– Ambra Barbera, Food & Quality Manager, SushiDog

Served’s work with partners doesn’t stop at setup. The team works closely with SushiDog and other partners to keep improving the product for kitchen teams and guests.

Common questions

Does SushiDog have an allergen menu?

Yes. SushiDog has a live, digital allergen menu, built by Served, for its UK sites. Guests can find it on the EAT map, in the SushiDog app, on SushiDog's website, or by scanning the QR code on the counter. They can then filter dishes by allergen or dietary requirement.

Does Served Source use AI to read spec sheets?

Yes, to support audits and human checks. Served Source scans each supplier spec sheet and shows the results side by side with the original, so a person checks every detail. The restaurant's team makes the final call.

What happens when a supplier changes a product?

The team swaps the product once in Served Source. It recalculates the ingredient list, allergens and nutrition for every dish that uses it, or only the dishes the team chooses, and the live allergen menu updates.

Can Served Source help with allergens outside the 14 major allergens?

Yes. Served Source keeps a full ingredient list for every dish, so ingredients outside the 14 major allergens, such as garlic and onion, can be searched across the whole menu. Restaurants can show ingredient lists to guests or keep them as a Kitchen Search for staff.
