L'air du temps

The Verdict: Two Michelin Stars, Vegetable-Driven, and Worth the Pilgrimage to Liernu

The most common misreading of L'air du Temps is that it is primarily a French fine dining restaurant with some Asian influence. It is not. Chef Sang-Hoon Degeimbre has built something closer to a plant-forward tasting experience, where vegetables sourced from an on-site farm of several acres are the actual subject of each plate, and fish or meat appears as a secondary note rather than the headline. If you arrive expecting a classic Franco-Asian luxury dinner, you will be recalibrating from the first course. If you arrive understanding the premise, you will find one of the most coherent kitchen-to-table sourcing arguments in Belgium — or, for that matter, in Europe.

L'air du Temps holds two Michelin stars (2024 and 2025), a place in La Liste's leading restaurants at 88.5 points in 2025, a Les Grandes Tables du Monde membership, and a ranking of 61st on Opinionated About Dining's European list in 2024. That is a consistent track record across multiple credentialing bodies, which tells you the kitchen is performing at a level the industry takes seriously across disciplines — not just within one evaluation framework. The Star Wine List recognition (White Star, 2023) also signals that the wine program is worth your attention alongside the food.

What Makes the Sourcing Argument Compelling

The farm at L'air du Temps is not a marketing prop. It covers several acres, requires a dedicated team to operate, and drives the daily composition of what arrives at the table. This matters for the explorer-minded diner because it means the menu is genuinely seasonal in a structural sense: the kitchen cannot reach for out-of-season imports without undermining the premise. What you eat at a Tuesday dinner in October will be materially different from what you eat on a Saturday in April. That is not a commonly reliable claim at this price point, where luxury kitchens often maintain the appearance of seasonality while sourcing globally.

The We're Smart recognition frames this correctly: Degeimbre's kitchen is one of the reference cases for a vegetable-first high-end restaurant format. When you pay €€€€ here, you are partly paying for the operational cost of that farm infrastructure , the team, the land, the seasonal risk , and for the translation of that raw material into technically precise cooking that draws on both French classical training and Korean culinary sensibility. That combination is less common than it sounds. For a direct point of comparison at a similar technical level, Atomix in New York City executes a Korean-influenced fine dining format with comparable precision, but operates in a very different ingredient and service context. L'air du Temps' singularity is rooted in where it is, not just how it cooks.

Atmosphere and What to Expect When You Arrive

Liernu is a small village in the Éghezée municipality of Wallonia , agricultural, quiet, far from Brussels traffic. The setting shapes the experience before you sit down. There is no urban noise bleed, no street energy, no background hum of a city neighbourhood. The ambient feel at L'air du Temps is deliberate and composed: the kind of room where the food and conversation hold the attention because nothing external competes for it. Diners who want a buzzy metropolitan energy are better served elsewhere. Those who want full focus on what is on the plate will find the quiet useful.

Service runs Tuesday through Saturday, dinner only, from 7pm to 8:30pm. The Sunday and Monday closure is firm. If you are planning travel from Brussels or further afield, factor in that this is an evening-only commitment in a rural location, so overnight accommodation nearby is worth arranging.

Booking and Access

Booking difficulty is rated Near Impossible. At two stars with a restaurant of this profile, tables are genuinely scarce. Plan well in advance , several weeks at minimum for a standard booking window, and potentially longer for weekend slots given the limited operating days. There is no walk-in culture at this level. Contact the restaurant directly and have alternative dates ready. If your target dates are unavailable, consider the broader Belgian two-star circuit: Boury in Roeselare and Hof van Cleve in Kruishoutem operate at a comparable level and may have more availability depending on your travel window.

For context on the wider Belgian fine dining circuit, Zilte in Antwerp, Willem Hiele in Oudenburg, and Bartholomeus in Heist each offer distinct profiles worth considering depending on your priorities. If you are in Brussels itself, Bozar Restaurant offers a different register of the city's fine dining options.

Practical Details

Dress code is not specified in available data, but at this price and award level, smart to semi-formal is the standard expectation across comparable Belgian two-star restaurants. Arrive dressed accordingly.
