Restaurant in Luxembourg, Luxembourg
Michelin-starred plants. Book it seriously.
Fields by René Mathieu earned a Michelin star in 2025 and holds a La Liste score of 82 points — Luxembourg's most credentialled pure plant and gluten-free tasting menu restaurant. René Mathieu is one of only two We're Smart Untouchable chefs globally. Book four to six weeks out minimum; demand has increased sharply since the Michelin award. Only book if the 100% plant-based format is what you want.
Yes — book Fields by René Mathieu if you are serious about plant-based fine dining and want a Michelin-starred experience that goes beyond token vegetable dishes. This is one of the few restaurants in Luxembourg, and arguably in Europe, where a 100% pure plant and gluten-free tasting menu is the entire proposition, not a concession to dietary preference. If you are coming from a meat-forward fine dining background and plant-based is secondary to you, Ma Langue Sourit or Léa Linster will serve you better. But if vegetables, wild herbs, and fruit are the point, Fields earns its Michelin star and its La Liste ranking of 82 points in 2026.
René Mathieu built his reputation over two decades at La Distillerie, where his former restaurant ranked number one in the We're Smart TOP100 for Leading Vegetables Restaurants in the World for two consecutive years (2020-2021). That credential matters because it is independently verified by a specialist ranking body, not a PR claim. He and Xavier Pellicer from Barcelona are the only two chefs to achieve We're Smart Untouchable status — a distinction awarded for sustained dominance at the leading of the plant-focused ranking. Fields is where that work continues, now with a Michelin star confirmed for 2025.
The address , 6 Rue de Trèves in Findel Sandweiler, just outside Luxembourg City , places the restaurant near the airport corridor rather than in the city centre. If you are flying in or out of Luxembourg Airport, the location is genuinely convenient. For city-based visitors without a car, factor in transport time before you book. The surrounding green countryside of the Grand Duchy is part of the kitchen's source logic: Mathieu works with small local growers, drawing on the seasonal produce of the region. This is not a style choice layered onto the menu , it is the menu's architecture.
The food at Fields is defined by colour, texture, and the full expression of plant ingredients rather than by imitation of meat-based formats. Vegetables, fruit, and wild herbs are treated as the primary material, not as garnish or accompaniment. For a returning guest, the menu will shift with the seasons, so what you encountered on a first visit will not map exactly onto a second. That seasonal variability is a reason to return, not a caveat. The La Liste score of 82 and the Michelin star together confirm that the kitchen's execution is consistent enough to justify repeat visits at this price tier.
At the €€€€ price range, Fields sits alongside Luxembourg's other top-end restaurants. The difference from most peers is that the price here buys a fully committed single-direction menu. There is no hedging between plant and animal protein. If you are bringing a guest who is not a plant-based eater, this is the most important thing to confirm before booking. Everyone at the table will be eating the same format.
Book as far ahead as possible , treat this as a hard booking, not an easy walk-in. Michelin-starred restaurants at the €€€€ tier in small-market cities like Luxembourg fill their covers quickly, and Fields draws an international audience in part because of its We're Smart credentials and Mathieu's profile in the plant-based fine dining world. The safest approach is to reserve four to six weeks out for a weekday dinner, and longer for weekend service. No booking method is specified in available data, so check the restaurant's direct contact channels. Phone and online booking details are not confirmed here , verify independently before relying on either.
The Michelin star was awarded for 2025, which means the restaurant is currently in its first full Michelin-starred year. Early months following a first star frequently bring a surge in reservation demand. Book sooner rather than later if Fields is on your list for this year.
If you visited Fields before the Michelin star was awarded (pre-2025), the experience you had may have been close to the current one in philosophy but the recognition has changed the booking dynamic considerably. A second visit is worth planning around the seasonal calendar , early spring and autumn are when plant-forward kitchens in Northern Europe tend to produce their most distinctive menus, as foraged wild herbs and transitional produce add range to the palette. For a returning guest, asking about the seasonal focus when reserving is worthwhile. The kitchen's emphasis on local small growers from the Grand Duchy means the menu has a genuine regional character that varies with the time of year.

Quick reference: Fields by René Mathieu , Michelin 1 Star (2025), La Liste 82pts (2026), 100% plant-based and gluten-free, €€€€, Findel Sandweiler (near Luxembourg Airport). Book 4-6 weeks out minimum; expect hard availability.
Solo dining is possible at a Michelin-starred tasting menu restaurant, and Fields' format , a set menu served to the whole table , suits solo guests well since there are no ordering decisions to make. At €€€€, the per-head cost is the same regardless of party size. If you are solo and want a more social counter-style setting, Fields may feel formal depending on the room configuration, which is not confirmed in available data. That said, solo diners who travel specifically for plant-based fine dining will find Fields one of the most purposefully built experiences of its kind in Luxembourg. For a slightly lower price point, Apdikt at €€€ is worth comparing.
Book at least four to six weeks out for a standard weekday booking, and further ahead for weekends. Fields earned its first Michelin star in 2025, and first-star restaurants in small markets typically see a significant demand spike in their debut Michelin year. The restaurant's international profile , built on We're Smart TOP100 rankings and René Mathieu's reputation as one of two We're Smart Untouchable chefs globally , means it draws visitors from outside Luxembourg, compressing availability further. Treat this as a hard booking and confirm your reservation method directly with the restaurant, as booking details are not confirmed in Pearl's current data.
Group bookings at €€€€ tasting menu restaurants require advance planning and, in most cases, direct contact with the venue to confirm capacity and any private dining options. Seat count and private room availability are not confirmed in Pearl's current data for Fields. For groups of four or more, the tasting menu format works well because the kitchen controls the pace and structure. Contact the restaurant directly to discuss group size before booking. If a group includes guests who are not committed to a plant-based menu, this is the most important conversation to have before confirming , Fields is 100% plant-based with no animal protein on the menu.
At €€€€ and with a Michelin star confirmed for 2025, the tasting menu at Fields is priced in line with Luxembourg's other top-tier restaurants including Ma Langue Sourit and Léa Linster. The difference is that Fields is fully committed to a plant and gluten-free format, so the value question is really about whether that is the experience you want. If it is, the La Liste score of 82 and the We're Smart Untouchable credential (one of only two chefs globally to hold this) confirm the kitchen is operating at a level that justifies the price. If plant-based fine dining is not your primary interest, the same price tier at Ma Langue Sourit or Léa Linster offers a broader protein range.
No dress code is confirmed in Pearl's current data for Fields. At a Michelin-starred, €€€€ restaurant in Luxembourg, smart casual is a safe baseline , jacket optional for men, but jeans and trainers would likely feel underdressed relative to the room. Luxembourg's top-end dining culture tends toward formal-relaxed rather than strictly black tie. If dress code matters to your group, contact the restaurant directly to confirm expectations before arrival.

A quick look at how Fields by René Mathieu measures up.
Solo diners who are serious about produce-led cooking will find Fields a rewarding choice. The €€€€ price point and tasting menu format suit focused, unhurried eating rather than social occasions, which works in a solo diner's favour. René Mathieu's Michelin-starred kitchen emphasises texture, colour, and ingredient precision — details that reward full attention. If solo fine dining in Luxembourg is your plan, Fields is the strongest single option in the city on that basis.
Book as early as possible — treat this like any Michelin-starred restaurant at the €€€€ tier in a small-capital city with limited comparable competition. Demand increased after the 2025 Michelin star was awarded, and availability will reflect that. A minimum of three to four weeks ahead is a sensible baseline; further out for weekend sittings or special occasions. Walk-in availability is not something to count on.
Groups are possible but require advance planning at this tier. The restaurant's format is a structured plant-based tasting menu, so groups need to be comfortable with a single shared format rather than à la carte flexibility. Smaller groups of two to four are the most natural fit for tasting menu dining; larger parties should check the venue's official channels to confirm capacity and seating arrangements. The address is 6 Rue de Trèves, 2632 Findel Sandweiler, Luxembourg.
Yes, if plant-based fine dining is something you actively seek out. Fields earned a Michelin star in 2025 and carries La Liste recognition at 82 points for 2026, which places it among documented high performers in its category. René Mathieu's former restaurant held the number one position in the We're Smart TOP100 for Best Vegetables Restaurants in the World for two consecutive years. At €€€€, you are paying Michelin rates — the case for value holds if the format (100% pure plant, gluten-free, seasonal) matches what you want.
A Michelin-starred restaurant at the €€€€ tier in Luxembourg warrants smart dress as a default. There is no documented dress code in the available venue data, but the format and price point align with what you would wear to any comparable starred restaurant in Western Europe: polished, not casual. Trainers and activewear are a risk at this level; a jacket for men and equivalent for women is the low-effort, safe call.
Keep this venue in your Pearl passport, rate it after you visit, and track it alongside every other place you collect.
