The delicious details

Restaurant Piloersemaborg occupies the only surviving 17th-century Groningen farm-borg of its kind, a 1633 estate at Den Ham with goats, sheep, an orchard, and a working kitchen garden. Chef Dick Soek has run the kitchen here since 2005, consolidating his earlier Leens venture into a single venue.

Soek learned a pared-back style during a stretch as a competitive cyclist in northern Italy, and he applies that minimalist approach to the produce of the surrounding province. The result is a short daily menu built around what suppliers and the garden have brought in that week.

Service runs informal under the historic timbers. Dishes carry the names of the producers behind them, a choice the chef committed to long before it became common in the region. Guests pay a single all-in price covering the menu, aperitif, wines, water, and coffee.

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

Sixteen named regional producers alongside the estate's own garden, orchard, and hunting association game. House-raised lambs, Wadden Sea fish, goat dairy, poultry, sheep cheese, and orchard fruit all trace to specific named farms. Italian technique with North Groningen ingredients. Menus rotate continuously; vegetable courses draw on the kitchen garden and historic orchard of fifty-four apple varieties.

How this restaurant rates
4 - Recognised

Piloersemaborg sources nearly all its ingredients from named regional producers in North Groningen and the Wadden coast, including Eemstuin for vegetables, Kemperkip via Piet Glas for poultry, Waddenmax for dairy, Visafslag Lauwersoog for auction-fresh fish, and Jachtvereniging Nimrod via hunter Tiemo van Straten for game. Seasonal cooking follows directly from this supply: the chef's published credo is to eat what the land offers and follow the seasons, and menus rotate continuously with what suppliers and the garden have brought in that week.

Responsible animal sourcing runs across most categories, with lambs raised on the estate and butchered by named processor Kroonvlees, goat dairy from Machedoux, sheep cheese from Groot Kabel and FBG, and North Sea fish via vessel UK158 alongside the Lauwersoog auction.

In independent editorial the chef describes throwing nothing away and keeping every step under his own hand, working through whole carcasses and channelling the orchard's fifty-four apple varieties, pears, plums, and currants into juices, ciders, and preserves through the year.

A We're Smart Green Guide listing recognises the kitchen's vegetable-led editorial positioning. Gault&Millau Netherlands named Dick Soek Artisan of the Year for 2020 and scores the restaurant 14 out of 20, recognising the same craft-led approach.

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 a planet rating 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.

Ratings of four or five planets 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.
