The delicious details

Brun is a small restaurant on the Steenweg in Mazenzele, where vegetables are the starting point for every plate. The kitchen cooks with the season and leans on local products wherever it can.

Dishes arrive to be shared, several plates at a time, in a warm and unforced room. The card changes regularly as produce comes and goes. Fish and meat sit alongside the vegetables rather than in front of them.

Chef and owner Stefan De Bruyne is a keen walker, runner and cyclist, and keeps water ready for cyclists and walkers passing the door on warm days.

Menu
What's on the table, and what's left off

Vegetables lead at Brun: the menu is built from a range of vegetable dishes, with fish and meat offered beside them. Vegetarian guests have a real choice across the card. The menu follows the season and changes regularly, so what reaches the table depends on what is good at the time. Plates are made to be shared, several arriving at once for the table to divide between them.

How this restaurant rates
2 - Engaged

The kitchen cooks with the season: the menu is built around what is available and changes regularly, so dishes track the harvest rather than a fixed card. Vegetables carry that menu, forming the structure of the offer, with fish and meat kept alongside rather than at the centre.

On the community side, the restaurant offers free water refills to cyclists and walkers passing through Mazenzele in warm weather, a standing gesture reported by the local press. Brun is also listed in the We're Smart Green Guide, the guide to vegetable led restaurants.

The impact dimensions

Local & direct sourcing✓

Seasonal cooking

Social impact✓

Plant-forward menu✓

Local sourcing is positioned as a value of the kitchen but no named supplier has been confirmed.

The restaurant's own site states that it cooks with local products wherever possible ("zoveel mogelijk lokale producten"), and the We're Smart Green Guide listing describes a sharing offer of locally grown vegetables. These positions are consistent but carry no named, traceable supplier.

No butcher, fishmonger or farm is named on any page retrieved. Third-party search summaries reference an organic grower in Steenhuffel (De Biokast), but this could not be confirmed on any page actually opened during this screening.

Strongest sourceWe're Smart Green Guide ↗

The menu changes regularly with the season and is built around what is available at the time.

Seasonality is the restaurant's stated organising principle. The homepage leads with "Seizoensgebonden gerechten" and "Bij Brun koken we met het seizoen mee", positioning the kitchen as cooking with the season rather than around a fixed card. The restaurant's own description states that the menu changes regularly because dishes are built around what is available, and the We're Smart Green Guide listing is consistent with this produce-led, rotating approach.

The change is tied to produce availability rather than left as decoration, which supports level 3. The restaurant's website does not publish dated or archived menus, so the full extent of the rotation across two seasons cannot be verified from web sources alone, which is why level 4 is not awarded.

Strongest sourceRestaurant submission

The restaurant offers free water refills to cyclists and walkers passing through in warm weather, reported by local press.

Local news outlet Goeiedag reported on 19 June 2025 that Brun offers free water refills to cyclists, walkers and passers by during warm weather. Owner Stefan De Bruyne, himself a walker, runner and cyclist, set up the practice to give something back to people passing through Mazenzele. The article notes that passers by are welcome during Friday and Saturday preparation hours even when the dining room is empty.

This is a described, open-ended community practice corroborated by an independent editorial source, rather than a single past event or generic community language. No evidence was found on fair employment or cause support and social supplier sourcing, so this sits in one of the three sub-areas of social impact.

Strongest sourcegoeiedag.be ↗

Vegetables are structurally the foundation of the menu and the centre of the restaurant's identity, with fish and meat beside them.

Vegetables are the restaurant's defining identity. The homepage states "Groenten staan centraal", and the We're Smart Green Guide, a specialist vegetable-focused guide whose listings require menus comprised of at least two thirds fruit and vegetables, carries Brun with the description of a sharing concept where you can choose from "a range of locally grown and organic vegetable dishes alongside meat and fish." The resto.be directory classifies the cuisine as both Gastronomic and Vegetarian and describes "a focus on organic vegetables without forgetting the fish and meat lover", and local press from June 2025 calls it a "groenterestaurant".

Animal proteins sit beside rather than in front of the vegetables, and the We're Smart listing indicates the menu structure has vegetables carrying at least two thirds of the offer. This supports level 4. The current menu is not published online, so the vegan share could not be verified from web sources, and level 5 additionally requires responsible sourcing of the remaining animal proteins, which is not evidenced.

How we score
The My Treats impact scale

Every restaurant is assessed against SEERO, our six-dimension sustainability framework — covering sourcing, seasonality, waste, animal products, social impact, and plant-forward cooking. Each finding is weighted by how strongly it is corroborated. The combined result is translated into an impact score from 1 to 5.

The five levels

SEERO is an acronym for Starting, Engaged, Endorsed, Recognised, Outstanding:

Starting First verified signals of sustainable practice.
Engaged Credible practice across two dimensions.
This place
Endorsed Meaningful practice across three or more dimensions.
Recognised Strong practice across four or more dimensions, with independent corroboration.
Outstanding Top-tier practice, confirmed by recognised third-party audit.

How a level is reached. Each level needs two things together: a minimum number of dimensions covered, and a minimum overall strength of evidence across them. A dimension only counts once its evidence is specific and substantiated — a passing mention doesn't qualify. Meeting only one of the two keeps a restaurant a level lower.

Scores of four or five require human validation and, at the top tier, an external audit. Scores are based on publicly available evidence and restaurant submissions at the time of assessment.

Self-declared Stated by the restaurant on its website, menu or in a submission. Plausible, but not yet independently corroborated.
Researched Found through independent research; one credible third-party source backs the claim.
Vouched Corroborated across more than one independent source. Some gaps may remain.
Audited Fully corroborated across independent sources or by a recognised third-party certification.
What the sourcing checkmarks mean
✓ Full check — independently verified: corroborated across more than one source, or audited / third-party certified (vouched or audited).
✓ Light check — self-declared or from a single source. Not yet independently verified.
