The delicious details

Oesterij is a working oyster and mussel farm in Yerseke, the shellfish town of Zeeland, run by the same family since 1906 and now in its fourth generation. The site brings together a hatchery, a shop, a tasting room and an information centre on the edge of the Oosterschelde.

Guests eat where the shellfish is grown. In summer a pontoon terrace sits out over the water, and staff walk visitors through the oyster ponds and the different beds the family works across Zeeland.

The appeal is simplicity and freshness: oysters in several varieties, mussels in season and generous fruits de mer platters, opened and served close to where they were harvested.

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

The menu is built around shellfish the family grows and serves. Oysters come in several varieties, from the Oesterij Special to Oosterschelde creuses, alongside mussels in season, Oosterschelde lobster and fruits de mer platters of prawns, cockles, periwinkles and North Sea crab. Much of it is served raw or simply dressed to let the fresh product lead, while dishes such as lobster bisque and gratinated oysters are prepared in the kitchen on site.

How this restaurant rates
2 - Engaged

Oesterij confirms responsible practice across three clear areas. Its shellfish is grown by the family itself in named Zeeland waters, including the Oosterschelde, the Grevelingenmeer, the Veerse Meer and the beds at Waterdunen, giving an unusually short and direct route from water to plate. The oysters and mussels are sown and harvested on designated plots in a way that limits disturbance to the seabed, a low-impact approach to raising shellfish. Mussels follow their natural season, and the range of oysters changes with what the beds yield through the year.

The Zeeland flat oyster served here is recognised by Slow Food (Ark of Taste), and the restaurant features in the Gault&Millau Netherlands guide.

Mussels are offered in season, and the oyster range changes with what the beds yield through the year.

The menu is shellfish-led and inherently seasonal: mussels are offered in season, and the family grows different oyster types across the year in different cultivation areas. Seasonality is driven by the harvest rather than by an explicitly rotating menu concept.

Strongest sourceoesterij.nl ↗

The restaurant serves shellfish it cultivates itself in designated Zeeland plots, with low-impact sowing and harvesting practices.

The restaurant serves only shellfish (oysters, mussels, lobster, crab), which it cultivates itself in designated Zeeland plots. Cultivation is described as sowing and harvesting on designated plots in a way that limits seabed disturbance, a low-impact aquaculture 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.
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.

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.
