The delicious details

Lisa Calcus opened Les Gribaumonts in 1993, straight out of hotel school in Namur, and has cooked here ever since. The kitchen works from the vegetable up: what is in season decides the plate, and the fish, meat and spices follow.

The room sits behind an eighteenth century facade in the Saint-Nicolas en Havré quarter, with large windows onto the kitchen and bar. Menus run from three to five courses, each with a wine pairing from a cellar Nicolas Campus draws entirely from European growers.

The carte is rewritten every fortnight. Most vegetables come from Les Folies Maraîchères, an organic market garden in Dour that sells direct to the kitchens it supplies, and they reach past the savoury courses: one dessert is built on parsnip, white chocolate and almond crumble.

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

Fixed-menu fine dining built on what the garden sends that fortnight. Menus run three to five courses, each paired with a wine from European growers only. Dishes are named for their preparations: turbot with black sesame and cauliflower, scallops with mushrooms and Jerusalem artichoke, red bream ceviche with vadouvan.

Dishes are named for their parts rather than their assembly: turbot with black sesame, cauliflower and yuzu; red bream ceviche with citrus and vadouvan; scallops with mushrooms, Jerusalem artichoke and vin jaune.

Vegetables set the direction and the protein is chosen to match, so a plate of fish, farmhouse poultry, game or a choice cut is built outward from what the garden sent that fortnight. Dishes are described by their component preparations, a fumet, a meat jus, a gambas butter, rather than as finished plates.

Vegetarian cooking is handled as an adaptation rather than a fixed section: the restaurant asks guests to mention at booking if they eat vegetarian or have an allergy, and adapts the dishes accordingly.

Most of the vegetables come from Les Folies Maraîchères, a certified organic market garden in Dour, in the same province, which sells direct to the kitchens it supplies rather than through a wholesaler. The carte is rewritten every fortnight and the kitchen buys only what is in season, which shows in menus that move from garden beans in summer to Jerusalem artichoke and skrei in winter.

The restaurant is listed in the We're Smart Green Guide, the international guide to vegetable-led cooking, whose entry notes the chef's practice of sourcing organic produce from farmers near Mons.

The impact dimensions

Local & direct sourcing✓

Seasonal cooking✓

Sustainable animal products

Plant-forward menu✓

One named local organic supplier confirmed: Les Folies Maraîchères market garden at Dour supplies the majority of vegetables direct.

One named, traceable local supplier is confirmed: the restaurant states that the majority of its vegetables come from Les Folies Maraîchères, a certified organic market garden at Dour, roughly twenty kilometres from Mons and in the same province. The producer is independently verifiable through its own site, the Hainaut Terre de Goûts provincial producer register, the biomonchoix.be organic directory and Biowallonie's BIO market-gardening suppliers guide, and it sells its entire output through short circuits direct to restaurants, so this is a direct producer relationship rather than anonymous wholesale.

The We're Smart Green Guide entry corroborates the practice independently of the restaurant, recording that the chef knows which local farmers to source the best organic-farming produce from. Producer proximity is strong: the garden sits in the same province as the restaurant, roughly twenty kilometres away.

Strongest sourceWe're Smart Green Guide ↗

Carte rewritten fortnightly; vegetables set the seasonal direction for fish, meat and spices.

Seasonality is communicated as the kitchen's guiding principle and is corroborated outside the restaurant. The restaurant's own site states that it works with ultra-fresh products always in season and that the carte is rewritten every two weeks; the JRE member listing records the same fortnightly cadence; Gault&Millau describes the cooking as original seasonal cuisine.

The We're Smart Green Guide entry records that the vegetables, chosen according to the season, are the starting point that guides the choice of fish, meat and spices. The rotation is independently observable: dish lists published across four separate guide and directory entries share almost no dishes in common, and they carry coherent seasonal markers, with garden beans and a summer catch in one edition and Jerusalem artichoke, parsnip and skrei in another.

Strongest sourcegaultmillau.be ↗

Farmhouse poultry, Iberian pork, wild fish seasonally, no named producers or certifications.

Animal products are central to the carte and carry partial sourcing signals but no verifiable traceability. The published menus name species, breeds and origins without a producer behind them: farmhouse poultry, Iberian pork, skrei loin, turbot, scallops, red bream, cod, veal sweetbread and a catch of the day.

Farmhouse poultry is an informal welfare reference used without certification, and skrei and the catch of the day are seasonal wild-fish signals. No butcher, fishmonger or farm is named for any animal category, and no MSC, ASC, organic or welfare certification is evidenced in any source.

Strongest sourceeating.be ↗

Vegetable-led cooking; vegetables guide fish and meat choices; vegetarian dishes available on request.

Genuine plant-forward intent is evidenced but the menu is not structurally plant-centred. The We're Smart Green Guide, a dedicated vegetable-led guide, carries a full entry for the restaurant; its entry and the JRE listing both record that the vegetables, chosen by season, are the starting point that guides the choice of fish, meat and spices.

The majority of vegetables come from a named organic market garden growing over 80 varieties; vegetables carry the compositions throughout, including a dessert built on parsnip with white chocolate and almond crumble. Against this: vegetarian dishes are available on request only and not as a menu section; no vegan option is mentioned in any channel; every signature dish across four separate sources is anchored on an animal protein.

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.
