Veggie Pret

Read the campaign story

Pret opened its original Veggie Pret experiment in 2016 after earlier audience polling. The brand later described making the initially temporary shop permanent and adding another location. Reporting in 2024 documented conversion of the remaining dedicated shops to regular Pret outlets. These stages belong to one family, not separate launch and closure case studies.

The history is more useful than an uncomplicated success story. A decision to continue an experiment does not by itself establish profitability, and a later format change does not prove that the original learning was worthless. The cited sources do not provide a controlled commercial evaluation. This case studies how a physical service can ask a public question and make the answer more concrete than a survey response.

Editorial interpretation: a temporary format allows people to encounter an actual proposition rather than only imagine one. It can reveal practical questions about choice, language and expectations that remain hidden in an abstract poll. Yet visitors to a distinctive launch may not represent ordinary demand. Novelty, location and publicity can affect who participates and how they respond, so the experiment needs an explicit boundary.

Editorial interpretation: the communication should explain whether the audience is being invited to explore, provide feedback or support a permanent change. Those are different relationships. A team can celebrate learning without implying that every trial will continue. Clear expectations make it easier to revise or end a format while preserving trust in the broader organisation and respecting the people who invested time in participating.

Define the decision the experiment will inform

Specify whether the team is testing menu comprehension, demand for a dedicated format or the usefulness of a different service arrangement. Avoid treating one favourable response as an answer to every question. A narrow test can be valuable even if it does not justify expansion. Record which conditions are unusual and which would need to hold in an ordinary operating environment.

Invite feedback without turning it into a vote

Explain how comments will be considered and what other constraints affect the decision. Do not promise that the most enthusiastic group will determine the outcome. Seek views from people who did not participate as well as those who did, while respecting privacy. A visible experiment can attract passionate supporters whose needs matter without representing everyone the service hopes to reach.

Plan the explanation for every possible ending

Prepare clear language for continuation, revision and closure before launching. Describe what was learned and what remains uncertain without retrofitting the story to make every outcome look triumphant. If an element moves into the main service, distinguish that from keeping the dedicated format. This protects the learning value of experimentation from becoming dependent on a permanent physical presence.

A small test for another brief

Proposed adaptation: show adult reviewers a fictional library’s temporary themed-shelf concept and a regular mixed-shelf alternative, using paper catalogues rather than a real pop-up or food service.

Measure whether the temporary framing improves discovery and whether participants understand that continuation is undecided. Compare responses from people interested and uninterested in the theme. Ask how they would interpret a later return to the regular layout, and revise the explanation if it makes ordinary learning sound like a broken promise.

Stop if the concept claims a permanent commitment, treats a self-selected sample as representative or implies health benefits from a category label.

• Keep available titles and access conditions identical.
• Label the themed layout as a limited experiment.
• Ask separately about navigation and desire for a permanent format.
