The delicious details

Le Mess occupies the former officers' mess of the Etterbeek Arsenal, a converted military site in eastern Brussels. Chef Antonio builds the menu around seasonal vegetables, drawing on Italy, France and Japan.

Much of the produce comes from small Brussels growers: oyster mushrooms raised on recycled coffee grounds, micro sprouts from an urban farm, herbs and vegetables from a city aquaponics site. Cheese comes from a Belgian goat and cow dairy, beer from two Brussels breweries, one of them in the Arsenal itself.

Croquettes, fries, lemonade and desserts are made in house, and the pasta is rolled fresh. Vegetarian and vegan dishes have their own sections of the menu, and gluten free items are marked throughout.

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

A market kitchen in the converted officers' mess of the Etterbeek Arsenal, with an à la carte menu of Belgian classics and seasonal plates built on what Brussels urban growers bring to market. Both starters and mains carry dedicated vegetarian sections. Croquettes, fries, lemonade and desserts are made in house; pasta is rolled fresh.

The menu runs two ways: Belgian classics that stay on year round, and seasonal plates that change with what the growers bring in.

Starters and mains each carry their own vegetarian section, from a summer vegetable tartare to fresh ricotta and aubergine ravioli. Vegetables get equal billing in the fish and meat dishes too, a ratatouille of seasonal vegetables or a courgette tian rather than a plain side. The group menus set a vegetarian main beside the fish and the meat at the same price.

Croquettes, fries, lemonade, iced tea and desserts are made in house. Vegan, gluten free and lactose free dishes are marked on the menu, and the full allergen list is available on request.

How this restaurant rates
4 - Recognised

Le Mess has confirmed practice across five areas of responsible cooking and sourcing.

Vegetables, mushrooms, herbs and sprouts come from named Brussels growers, among them an urban aquaponics farm and a cooperative that raises organic oyster mushrooms on recycled coffee grounds; cheese comes from a Belgian goat and cow dairy and beer from two Brussels breweries. Half the menu turns over with the growing season, built on what those producers bring to market. The kitchen works to a stated zero waste policy, and several of its suppliers are built on circular production, turning spent coffee grounds into mushrooms and raising fish and vegetables in a single loop. Fish is sourced from responsible fishing and meat from regional producers, under the criteria of the city's Good Food label. That mushroom cooperative is a social enterprise created to build stable employment in Brussels, and the coffee is bought on fair trade terms.

The restaurant holds Brussels' Good Food label at its top level of three toques, and it is listed in the We're Smart Green Guide.

Multiple named local suppliers across vegetables, mushrooms, herbs, dairy, grains, beer and soft drinks.

Multiple named, traceable local suppliers are evident across vegetables, mushrooms, herbs, dairy, grains, beer and soft drinks. The kitchen page names PermaFungi, Eclo, Urbi Leaf, Bigh and Interbio for produce; Graines de Curieux for Belgian quinoa; Chevrerie du Cadeau for dairy; and Brasserie de la Senne, Brasserie Cohop and Kefir Eau Vertueuse for drinks. Several are small Brussels producers bought from directly.

The Good Food label listing independently confirms that products are largely locally sourced and names Brussels mushrooms and terroir meats. Vegetables, mushrooms, herbs, dairy, grains, beer and soft drinks across around two-thirds of the key categories are demonstrably local.

Part of the menu rotates seasonally with what urban growers bring to market; Belgian classics are year-round fixtures.

The menu structure is documented consistently: on one side Belgian classics that stay year-round (croquettes, filet americain, Irish beef, dame blanche), on the other seasonal dishes that change with what urban farms and growers bring in. The current autumn menu carries a summer vegetable tartare, a ratatouille of seasonal vegetables, a fig salad and a seasonal sorbet, with a seasonal beer on the drinks list.

The Good Food label listing describes this explicitly, noting smaller dishes that vary with the seasons. Belgian food editorial recorded a seasonal kitchen with a winter menu built on Belgian quinoa and winter purslane.

Strongest sourceGoodfood.brussels ↗

Zero waste policy stated; suppliers PermaFungi and Bigh operate circular production models; in-house made goods reduce packaging.

A zero waste policy is stated on the restaurant's own site, recorded by the Good Food label as a direction of travel, and the We're Smart Green Guide listing describes waste management practice. In-house production of croquettes, fries, lemonade, iced tea and desserts reduces bought-in packaging, and fresh pasta is rolled on site.

Two named suppliers are themselves circular operations. PermaFungi raises organic oyster mushrooms from recycled coffee grounds, producing a tonne of mushrooms a month from five tonnes of grounds. Bigh operates an aquaponics farm raising fish and vegetables in one closed loop; Eclo grows mushrooms and herbs on the same circular principle.

Strongest sourceGoodfood.brussels ↗

Fish from responsible fishing and local aquaponics; cheese from a Belgian dairy; meat from regional producers; no welfare certification on most products.

Two animal product categories have named suppliers with documented sustainability. The Good Food label records fish from responsible fishing and terroir meats as the basis of the offer. The kitchen page names Chevrerie du Cadeau as the supplier for goat and cow dairy, and Bigh, a Brussels aquaponics farm, raises fish alongside vegetables. The autumn menu specifies North Sea fish for the fish and chips and farm chicken for the Caesar, both cooked at low temperature.

The scope of traceability does not extend across all animal products. No MSC, ASC or organic certification was found; the seared tuna steak carries no species or catch method detail; and the beef in the two highest-priced mains is Irish while the pluma is Iberian, named by country only.

Strongest sourceGoodfood.brussels ↗

PermaFungi, the mushroom supplier, is a social cooperative creating stable employment; coffee is fair trade from Mano Mano.

One sub-area, social supplier sourcing, carries named verifiable commitments. PermaFungi is described by the restaurant as a cooperative with a social purpose; the Good Food directory independently corroborates this, recording a social cooperative of the circular economy that produces mushrooms while creating stable employment. Coffee is named as Mano Mano and described on the kitchen page as fair trade, respecting people and the environment.

Strongest sourceRestaurant submission

Vegetarian dishes in separate starters and mains sections; vegan items marked throughout; vegetables get equal billing in fish and meat dishes.

Vegetarian dishes are a standing part of the offer and vegan dishes are marked on every menu. The kitchen page positions the restaurant with the line Vegetables first and states that vegans and vegetarians are more than welcome. The autumn carte carries a dedicated VEGGIE heading in both starters and mains, with the menu legend marking vegan dishes alongside gluten-free and lactose-free. Vegetables are given real billing inside animal dishes: a ratatouille of seasonal vegetables, a courgette tian, green beans with aubergine and confit tomato, or baby spinach. Both group menus at 55 and 65 euros set a vegetarian main beside the fish and the meat at the same price.

The restaurant holds a We're Smart Green Guide listing, which marks this dimension covered irrespective of its own score.

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.
Endorsed Meaningful practice across three or more dimensions.
Recognised Strong practice across four or more dimensions, with independent corroboration.
This place
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.
