The delicious details

September sits on a corner of the Baffinstraat in De Baarsjes, run by three friends who previously worked together at Alex & Pinard in east Amsterdam. The kitchen builds a compact menu around biodynamic produce, with vegetables taking the lead and animal proteins chosen for quality rather than volume. Candlelit tables, high ceilings and greenery give the small room a living room warmth that suits long evenings over wine and shared plates.

Bread arrives from neighbouring Ulmus Bakkerij, vegetables from Smaak Groenten and wines through Pieksman, Amsterdam's first exclusively organic and biodynamic wine importer. The short wine list centres on natural and biodynamic bottles from small producers, making the glass as considered as the plate.

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

A compact seasonal menu that rotates weekly, centred on biodynamic vegetables with meat and fish offered selectively for quality. Past dishes include raw sea bass with white almonds, skate with beans and cabbage, and duck with potato purée. Vegetarian options form a substantial share each week.

How this restaurant rates
2 - Engaged

The kitchen has confirmed strong practice across two areas of responsible cooking, supporting a two-planet rating.

Local and direct sourcing rests on named partnerships with three producers. Vegetables arrive from Smaak Groenten, bread from neighbouring Ulmus Bakkerij and wines through Pieksman, an Amsterdam-based importer dealing exclusively in certified organic and biodynamic bottles. These short supply chains keep the origins of key ingredients traceable. Seasonal cooking is a defining feature: the menu changes weekly, following what is available from local growers and reflecting the founders' connection to the harvest season.

The 360 Eat Guide has listed September for its seasonal, locally grounded approach to cooking.

Three named suppliers provide vegetables (Smaak Groenten), bread (Ulmus Bakkerij), and wines (Pieksman Wijnimport).

Three named local suppliers confirmed: Smaak Groenten for vegetables, Ulmus Bakkerij (neighbouring sourdough bakery using organic ingredients) for bread, and Pieksman Wijnimport (Amsterdam based, exclusively certified organic and biodynamic wines) for the wine programme. The restaurant positions itself around local and seasonal sourcing as a founding principle. These short supply chains keep the origins of key ingredients traceable.

Meat and fish sourcing is described in quality terms ('we prefer one good meat dish over multiple mediocre ones') but no specific meat, fish or dairy suppliers are named. Approximately three of the main ingredient categories (vegetables, wine, bread) have named local or regional provenance.

The menu changes weekly, shaped by what is in season and available from local growers.

The menu changes weekly, confirmed by multiple sources including the De Westkrant editorial interview with the owners and the 360 Eat Guide listing. Seasonality is a founding principle: the restaurant is named after September, described by the founders as the month of harvesting grapes, vegetables and other produce central to their kitchen.

Menu items observed across sources (raw sea bass, skate, Jerusalem artichoke, duck with stewed pear) reflect seasonal produce. The 360 Eat Guide recognises the seasonal approach as a core feature. Weekly rotation is substantially above the quarterly minimum for this score level.

Named species and a quality-over-quantity philosophy guide the restaurant's selective meat and fish approach.

The restaurant serves meat (duck, roast beef, pork schnitzel) and fish (sea bass, skate, mackerel) but takes a deliberately selective approach. The De Westkrant editorial interview quotes the owners: 'We have rather one good meat dish than multiple mediocre ones. If you choose meat, you must truly taste how special it is.'

Specific species are named on the menu. The quality over quantity philosophy and named species represent a partial sourcing signal for this engagement level.

Biodynamic vegetables sourced from Smaak Groenten form a substantial part of the weekly menu alongside animal proteins.

The 360 Eat Guide describes September's vegetables as 'the main event' on the bistro menu, and the restaurant sources biodynamic vegetables through Smaak Groenten as a named supplier. The menu appears to centre on vegetables as the primary focus.

The menu also features substantial animal protein dishes: raw sea bass, skate, duck, roast beef, pork schnitzel, and mackerel are all confirmed across sources. Vegetarian options are confirmed by multiple sources. Estimated 30 to 50% of the menu's mains are plant-centred.

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).
