The delicious details

Rizoom serves one set menu, built on Japanese technique and a kitchen that ages, ferments and cooks over open fire. Chef Yves Kerckhoffs works ingredient by ingredient, looking for the moment in the season when each one is at its best, with vegetables setting the rhythm of the micro seasons.

24 guests are served each evening, eight of them seated at the kitchen itself, so the cooking happens in front of the people eating it. The menu runs to 13 or 15 small servings, with broths, reductions and oils made in house doing the work.

Fish arrives whole and is aged on site, and several parts of one fish can appear on a single plate. Fish, shellfish, poultry and aged meat come from European suppliers the kitchen chooses on their practices.

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

A fixed omakase menu of 13 or 15 servings, led by seasonal vegetables and European fish and meat. Ageing, koji and fermentation run through it. The kitchen makes stocks, jus and oils in house, working from whole ingredients with minimal processing.

One omakase menu is served each service: 13 or 15 servings on Friday and Saturday evenings, and a shorter version earlier in the week and at Friday lunch. Dry ageing, koji and fermentation run through it, and umami is carried by broths, reductions, oils and herbs rather than by bought flavourings.

The kitchen works from whole produce with little processing in between. Fermentations are set up on site, stocks and jus are made from scratch, including a jus built from roasted chicken wings, and a single aged fish can be served in four parts with fresh wasabi and a pickle. Vegetables guide the menu through the micro seasons alongside European fish, shellfish, crustaceans, poultry and aged meat.

The menu is fixed and the kitchen is clear about what that means. It states that vegetarian and vegan guests, and guests with a fish allergy, cannot be served. Shellfish and crustacean allergies and gluten, soy and lactose intolerances can be accommodated where cross contamination is not a concern, and severe gluten and soy allergies cannot.

Health-intentional kitchen✓

Specific health practices named in at least one sub-area
Vouched

The kitchen builds flavour through ingredient handling rather than stated health intent. Fermentations are set up on site, fish is aged whole, and umami comes from broths, oils and reductions instead of bought products. Dishes use whole produce with minimal processing: a single aged fish can appear in four parts with only wasabi and pickle.

Seasonality is structural rather than decorative. Vegetables lead the kitchen through the micro seasons, the menu is built around the moment each ingredient is at its best, and even the number of servings changes with the time of year.

The kitchen also works to get the most out of what it buys. Fish arrives whole and is aged on site, several parts of one fish can appear on a single plate, jus is built from roasted chicken wings, and koji, fermentation and other preserving techniques are part of daily practice rather than an occasional flourish.

Fish, shellfish and aged meats sourced from suppliers within Europe on stated practice basis.

Fish, shellfish, crustaceans, meat and poultry come from suppliers within Europe, chosen deliberately on their practices. The kitchen seeks local products where possible and without excess.

Vegetables lead the menu through micro seasons; the number of servings changes with the season.

Vegetables guide the menu through the micro seasons, and the menu composition changes throughout the year. The evening omakase runs to 13 or 15 servings depending on the season, and dishes are built around a specific characteristic of an ingredient or its moment in the season.

The Michelin Guide, Gault&Millau and the Culinaire Ambiance feature of 28 June 2026 independently describe seasonal sourcing as central to the cooking, with seasonal vegetables and products shaping what reaches the table.

Koji, fermentation and dry ageing are signature techniques; whole fish and bones become jus and stocks.

Koji, fermentation, dry ageing and open fire are the kitchen's core preserving techniques. The restaurant sets up its own fermentations, ages its own products and develops its own flavour makers in-house.

Whole ingredient use is the practice: four parts of one aged fish appear on a single plate with only fresh wasabi and a pickle, and jus is built from roasted chicken wings. Vegetables, broths, oils and reductions carry umami instead of bought products.

Fish, shellfish and meats come from European suppliers; species include hamachi, brill, turbot, mackerel and halibut; dry ageing is the handling method.

The restaurant's own kitchen page names fish, shellfish and crustaceans as sustainably farmed and caught, combined with aged meats and poultry from European suppliers. Specific species are named across coverage: hamachi, brill, turbot, sea bream, mackerel and halibut.

Dry ageing is the handling method named across sources. The Michelin Guide independently describes the chef working with sustainably caught fish, shellfish, poultry and aged meats.

Respect for ingredients and team work-life balance are named as equally important priorities.

Respect for the ingredient and a healthy work-life balance for the team are held to be equally important by the kitchen. The restaurant seats 24 guests per service with eight positioned at the kitchen itself, so direct contact between the chef, his team and guests shapes each evening.

Vegetables lead the menu through micro seasons; the kitchen offers no vegetarian or vegan main.

Vegetables guide the menu through the micro seasons and lead the kitchen's rhythm. The menu is built on European fish, poultry and aged meat alongside seasonal shellfish, crustaceans and vegetables, which places plants beside the proteins rather than at the centre.

The restaurant states plainly that vegetarian, vegan and fish-allergic guests cannot be served, as they ask for too many menu adaptations. The We're Smart Green Guide listing withholds endorsement and hopes the chef will in future shift his focus to plant-forward cooking.

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.
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.

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.
