The delicious details

Castor opened in 2016 in a building of concrete, glass and cedar on the Kortrijkseweg outside Waregem. The house line is that the product is the star: all about the food, never about the fuss.

Maarten Bouckaert buys as close to home as he can and keeps direct ties with the growers and farmers he works with. Two menus then run side by side at every service. One takes in land and sea, from North Sea crab to veal used nose to tail; the other, Root, Herb & Greens, is built on vegetables alone and runs to the same length and nearly the same price.

Both follow what is in season, and some producers are named on the card: aubergine from Vermeulen, strawberries from Four de Freeze-boer at Dentergem, a quarter of an hour up the road.

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

Service is by tasting menu, four to seven courses, in two parallel versions. The land and sea menu runs North Sea fish and shellfish with a veal course taken nose to tail, while Root, Herb & Greens mirrors the same length and cadence entirely on vegetables.

Service is by tasting menu, four to seven courses, in two parallel versions. The land and sea menu leans on North Sea fish and shellfish, with a veal course taken nose to tail.

Root, Herb & Greens runs the same length on vegetables alone, each dish titled by the ingredient that carries it: heirloom tomato with pecorino and caper, Nantes carrot with chermoula and hemp, cauliflower with mushroom and sesame.

Sauces are the signature, made in the kitchen: braised pork cheeks with a cuttlefish gravy and a reduction of Rodenbach beer. Vegetarian guests are served a complete menu of their own; vegan dishes are not part of the offer.

How this restaurant rates
4 - Recognised

Sourcing stays close to home. Producers are named on the card, including strawberries from Four de Freeze-boer at Dentergem and aubergine from Vermeulen, and the kitchen keeps direct ties with the growers and farmers it buys from. The menus follow the season, moving from spring asparagus and morels through high summer tomato, pea and strawberry. On waste, the veal course is taken nose to tail, and as a member of the North Sea Chefs collective since 2013 the kitchen commits to cooking bycatch and undervalued North Sea species and to respecting fishing seasons.

Vegetables carry a menu of their own, Root, Herb & Greens, at the same four to seven courses as the land and sea menu. The restaurant is listed in the We're Smart Green Guide, which records vegetables as a layering presence through the cooking.

Named, traceable local producers appear on the published menus, including strawberries from Four de Freeze-boer at Dentergem and aubergine from Vermeulen.

Named, traceable local producers appear on the published menus, which places this at partial evidence of local sourcing. The dish titles credit strawberries to Four de Freeze-boer and aubergine to Vermeulen; Four de Freeze-boer is independently verifiable as a strawberry grower at Dentergem, about 15 km away, on the Flemish short chain platform Lekker van bij ons. Regional seafood is a second traceable channel: the chef is listed on the North Sea Chefs member roster, whose members work with fish landed by Belgian and Dutch fishermen, and the published menu runs North Sea crab and a catch of the day. Michelin's dish description names Rodenbach of Roeselare, about 20 km away, used in cooking.

The positioning is corroborated outside the restaurant: independent coverage describes the chef as an ambassador for the short chain who keeps close ties with his suppliers and buys as locally as he can, and his own site states that he selects high quality regional products.

Most dishes change with the season and seasonality is communicated as a guiding principle.

Most dishes change with the season and seasonality is communicated as a guiding principle. Rotation is visible across three independent snapshots of the menu rather than claimed: Gault&Millau describes white asparagus with morels and carnaroli, a spring composition; the current published menus are summer throughout, with heirloom tomato, Nantes carrot, courgette, green pea, elderflower, strawberry and a course named Summer in Green; and Michelin describes a further dish of pork cheeks with cuttlefish, cockles and mussels.

The restaurant states pure seasonal cuisine with respect for the land as its operating principle and independent coverage reports that the chef adjusts the menu according to the seasons and buys only the best seasonal products from local growers and farmers. North Sea Chefs members additionally commit to respecting fishing seasons.

Two concrete practices are named in the food waste sub area: cooking bycatch and undervalued fish species as a North Sea Chefs member, and the veal course taken nose to tail.

Two concrete practices are named in the food waste sub area. The chef appears on the North Sea Chefs member roster in the 2013 cohort; the collective was founded in 2011 and its members commit to cooking fish of lesser known and undervalued species and bycatch, and the published menu titles its veal course From Nose to Tail, a stated whole animal preparation. In the energy sub area the chef interview records electric vehicle charging on the car park.

The seafood category carries a real, independently verifiable commitment to North Sea fish, but the dimension is held at level 2 by high impact commodities (abalone and caviar) carried without a sustainability qualification.

The seafood category carries a real, independently verifiable commitment. The chef is listed on the North Sea Chefs member roster in the 2013 cohort; members commit to lesser known and undervalued species and bycatch from Belgian and Dutch fishermen, respect for fishing seasons and respectful preparation, and a chef interview reports that he serves only North Sea fish. The published menu is consistent with this in parts, running North Sea crab and a catch of the day, and the veal course is titled From Nose to Tail.

Against that, the same menu carries an abalone course and a 10 g Osetra caviar supplement, neither of which is a North Sea product and neither of which is published with a farm, certification or other sustainability qualification; the rubric caps the dimension at 2 where a high impact commodity is served without a named sustainability qualification.

Social and community themes appear in the restaurant's positioning through its owner-run structure and direct ties with suppliers.

Social and community themes appear in the restaurant's positioning through its owner-run structure and direct ties with suppliers. The restaurant is owner run, opened in 2016 by the chef with a hostess leading the dining room, and independent coverage describes service standards and a settled front of house team. The chef is an ambassador for the short chain who keeps close ties with growers and farmers, and his North Sea Chefs membership connects him to Belgian and Dutch fishermen through the collective's knowledge exchange.

A complete vegetable menu, Root, Herb & Greens, runs in parallel with the main menu at every service, at the same length and nearly the same price.

A complete vegetable menu runs in parallel with the main menu at every service, which is meaningful plant presence on a mixed menu. The restaurant publishes two standing tasting menus of equal standing: the land and sea menu, and a named vegetarian menu, Root, Herb & Greens, running the same four to seven courses at within five euro of the same price, with its own dishes titled by the vegetable that carries them, among them heirloom tomato with pecorino and caper, Nantes carrot with chermoula and hemp, cauliflower with mushroom and sesame, aubergine from Vermeulen, and a course named Summer in Green.

That is well beyond a handful of vegetarian dishes. The We're Smart Green Guide lists the restaurant and records that vegetables play a layering role through the preparations, citing a scallop dish built on salsify and chicory.

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.
