The delicious details

De Wereld van Jansje pairs an all-day lunchroom with a fair-trade gift shop in the middle of Haarlem's Grote Houtstraat. It is an initiative of Doopsgezind Haarlem and the Hartekamp Groep, and for close to two decades it has built its work around a simple idea: hospitality and social purpose belong together.

The lunchroom is run by a team of twenty-nine people with different talents and abilities, who prepare and serve the food. Guests reach it through the shop, which opens onto a calm inner courtyard with garden seating.

The kitchen keeps things homemade, from soups to pies, and works with fresh, organic and, where possible, local ingredients. Plant-based cooking sits at the centre of the menu, alongside vegetarian dishes and coffee with cake.

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

An all-day lunchroom serving organic plant-forward lunches as à la carte dishes, vegan burgers with homemade sauces, vegetarian salads with named ingredients such as almond and goat's cheese, and daily soups and pies prepared in-house from fresh, local and organic materials. The kitchen does not rely on pre-made bases.

The menu leans firmly plant-forward, built around vegetable-led lunches such as a vegan burger made from pumpkin and carrot with vegan mayonnaise, and salads like baked goat's cheese with almonds. Vegetarian and vegan choices run throughout, and the food served in the lunchroom is organic.

The kitchen prepares its soups, pies and dishes in-house rather than relying on pre-made bases.

How this restaurant rates
3 - Endorsed

Ingredients are chosen with care, with a stated preference for local produce and a lunch menu the kitchen keeps organic. The food is strongly plant-forward, giving vegetable-led and vegan dishes a central place on the menu rather than treating them as an afterthought.

Its clearest strength is social. The lunchroom is a working place for twenty-nine people with different talents and abilities, created together by Doopsgezind Haarlem and the Hartekamp Groep, so that every visit supports a meaningful workplace.

Plant-forward menu

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.
This place
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.
