The delicious details

Set inside the oldest surviving water tower in the Netherlands, a rijksmonument dating to the 1870s, Restaurant De Watertoren occupies a striking piece of Rotterdam's industrial heritage overlooking the historic drinking water basins of De Esch.

Owner Richard Toonen built the kitchen around what he calls 'nieuwe Hollandse keuken': a foundation of locally sourced Dutch ingredients shaped by the bold flavours of East Asian and South American cooking. Fish arrives directly from Scheveningen harbour; Dutch artisan cheeses like Tynjetaler from Friesland feature alongside house-fermented kimchi and chili sauce.

The menu is deliberately small, changing with the seasons. Around a third of the dishes are fully vegan, including a faux gras with Granny Smith chutney that reviewers describe as nearly indistinguishable from the original.

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

A compact, season-driven menu split between fish, meat, and fully plant-based dishes, grounded in North Sea catch from Scheveningen and artisan cheeses like Tynjetaler from Friesland. East Asian and South American influences run through, from sriracha popcorn to tempeh gado gado and house-made kimchi. Around one-third of the menu is fully vegan, from the signature faux gras to seitan and tofu-led mains.

De Watertoren grounds its cooking in seasonal Dutch ingredients, with fish sourced directly from Scheveningen harbour and artisan producers like Tynjetaler cheese from Friesland named on the menu. The kitchen's fermentation practice, producing house-made kimchi and chili sauces, reflects a preservation-oriented approach. Around a third of the menu is fully vegan, and the restaurant opts for faux gras rather than traditional foie gras.

Plant-forward menu

Fish from Scheveningen harbour and cheese from Friesland feature on the menu, with local sourcing confirmed for approximately two of five key ingredient categories.

Fish is sourced directly from Scheveningen harbour on the North Sea coast, and the menu names Tynjetaler, an artisan cheese from Friesland. The kitchen's 'nieuwe Hollandse keuken' philosophy centres local Dutch ingredients as a foundation for its fusion cooking.

De Buik van Rotterdam independently describes this local sourcing approach. However, most ingredient categories (meat, vegetables, grains) lack named suppliers, and the restaurant does not publish a supplier list.

Two of approximately five key ingredient categories show named local or regional sourcing, meeting the approximate 30–40% threshold. The claims rely partly on self-declared sources; independent corroboration from De Buik van Rotterdam exists but is surface-level.

Menu changes seasonally, confirmed by independent reporting; the small menu format supports responsive sourcing.

The restaurant describes its cooking as driven by 'smaken van het seizoen, lokaal' (seasonal flavours, local). De Buik van Rotterdam's coverage confirms the seasonal approach.

Menu items observed across different periods show variation. The deliberately small menu format supports seasonal flexibility by allowing the kitchen to respond to ingredient availability.

Around one-third of the menu is fully vegan, with plant-based starters and mains built on seitan, tofu, and seasonal vegetables integrated throughout.

Approximately one-third of the menu is fully vegan, including starters (faux gras, gua bao, gado gado) and mains built on seitan, tofu, and seasonal vegetables. The restaurant uses tempeh, mushrooms, and plant proteins prominently.

Vegan and vegetarian options are integrated throughout the menu rather than relegated to a separate section. Menu analysis from TheFork and HappyCow confirms plant-based options at approximately 30–35% of the offering.

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.

Self-declared Stated by the restaurant on its website, menu or in a submission. Plausible, but not yet independently corroborated.
Researched Found through independent research; one credible third-party source backs the claim.
Vouched Corroborated across more than one independent source. Some gaps may remain.
Audited Fully corroborated across independent sources or by a recognised third-party certification.
What the sourcing checkmarks mean
✓ Full check — independently verified: corroborated across more than one source, or audited / third-party certified (vouched or audited).
✓ Light check — self-declared or from a single source. Not yet independently verified.
