The delicious details

Triptyque occupies the basement of Wateringen's old town hall, in the heart of Westland, Europe's largest greenhouse horticulture region. Chef Niven Kunz and his partner Virginie van Bronckhorst-Kunz built the kitchen around an 80/20 principle in which vegetables and fruit fill roughly four-fifths of every dish, with fish or meat playing a careful supporting role.

The room follows the same restraint as the kitchen, with menus printed on tomato pulp paper and dried flowers in place of cut bouquets. Service moves at the pace of a tasting menu and reservations sit at the centre of the experience, with dinner served Wednesday through Saturday and a tasting-only format on Friday and Saturday evenings.

Niven, a co-founder of Dutch Cuisine and once the youngest Dutch chef to earn a Michelin star, sources produce across Westland and Midden-Delfland and pours an exclusively Dutch wine list.

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

The kitchen leads with vegetables, with roughly 80% of each plate composed from produce such as tomatoes, radishes, peppers and strawberries drawn from Westland and Midden-Delfland, and fish or meat playing a focused supporting role. Tasting menus run to three or five courses and shift with what local growers bring to the door. A fully plant-based menu is composed on request, and guests with food intolerances are asked to share details 24 hours ahead.

Local and direct sourcing sits at the centre of the kitchen, with vegetables drawn from growers in Westland and Midden-Delfland and Niven Kunz regularly travelling the region to visit suppliers. Seasonality follows the same rhythm, with the tasting menu shifting in line with what local producers bring through the door.

Low-waste and circular thinking runs through the operation, from the food-waste prevention recognised by the Michelin Green Star award through to deliberate choices such as menus printed on tomato pulp paper and dried flowers used in place of cut bouquets. Fish and meat form a small share of the plate, carefully selected by the kitchen.

A plant-forward menu is the restaurant's defining identity, with the 80/20 concept giving vegetables and fruit the leading role on every plate and a fully plant-based version available on request. The cellar is exclusively Dutch, a hyper-local wine programme that few peers attempt at this level. The restaurant carries a Michelin Green Star from the Netherlands 2025 selection in addition to a regular Michelin star for cooking, is a member of Dutch Cuisine (co-founded by chef Niven Kunz), and ranks 24th in the We're Smart Green Guide's 2025 Top 100 with a Pure Plant Choices designation; Gault & Millau named it Vegetable Restaurant of 2026.

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.
