The World’s Best Sustainable Restaurants

By Alexa Scott-Dalgleish

Eat, drink and be merry. Especially when you can do so in one of these impeccable eco-eateries.

Haoma - Bangkok, Thailand

Haoma is the creation of chef-owner Deepanker Khosla – known as DK – and is situated in the heart of Thailand’s capital city. The idea started with an online course in Aquaponics and grew in less than a year into the country’s first urban farm and zero-waste restaurant, with a menu of the highest quality ingredients grown in the restaurant’s organic farm in Chiang Mai or on-site, in its two-storey central greenhouse. 

This vast green lung mimics the cyclical nature of a healthy ecosystem: rainwater is collected to grow fish which are fed with food made from the kitchen’s organic solid kitchen waste. The fish excrement enriches the water with nutrients and enzymes which in turn is used to irrigate Haoma’s Aquaponics system, which supports 20 varieties of plants, herbs and edible flowers. Both fish and plants end up on the menu, crafted into gastronomic works of art with an Indian twist.

Mil Centro - Andes Mountains, Peru

Peru’s gastronomic reputation precedes it and Mil Centro is one of the newer openings on the scene ensuring that this isn’t about to change anytime soon. It is the second project from star Peruvian chef, Virgilio Martínez, whose flagship Lima-based restaurant is a regular on the ‘World’s Best Restaurants’ List, perched 3,500 metres above sea level in the Sacred Valley above an Incan archaeological site. The swirling complex of multi-tiered terraces was used by the Incas as an agricultural research station – a fitting heritage celebrated by a Martinez whose farm-to-table menu is packed with indigenous Peruvian ingredients, many of which are grown on-site. 

Mil Centro includes a biological and cultural research centre devoted to the exploration of the Andes’ product biodiversity and ancient techniques; a flavour laboratory that researches cacao chuncho, a wild species of cacao that grows in the city Quillabambo; and a micro laboratory dedicated to ferments, distillates and macerated liquors based on local species. Even the buildings themselves are crafted using local materials and resources, and the skills of native craftsman. The result? A highly authentic dining experience that gives diners a privileged insight into the culture, produce and identity and this historic Peruvian region.

Septime - Paris, France

This Parisian bijou bistro from chef Bertrand Grébaut is one of the most sought-after restaurants in the city and a paradigm of sustainable excellence. The menu is 80% vegetarian and the small quantities of meat and fish that make their way onto it are strictly free-range, ethically reared, sustainably-sourced and bought in their entirety, where Grébaut dabbles in experimental broths and terrines to ensure that even the most unconventional cuts don’t go to waste. This same level of detail and refinement can be seen in its elegant interiors and beautifully crafted menu, which earned it its first Michelin star in 2014.

99% of the products are sourced on French soil where great emphasis is placed on the fair and ethical treatment of farmers and suppliers: seafood is sourced from a supplier who deals directly with small-scale French fishermen and pays 20% more than the market price, whilst Grébaut often asks farmers to plant special vegetables with a guarantee to buy all of the produce at the best price. Septime also works with Farm Africa and an organisation called Ernest, which links restaurants with charities tackling food poverty.

Narisawa - Tokyo, Japan

Chef Yoshihiro Narisawa and his eponymous two-Michelin starred restaurant are pioneers on the sustainable gastronomy scene, renowned for developing a new genre of cuisine known as “innovative Satoyama”. Satoyama is a term for the area between mountain foothills and arable flat land and, when referring to gastronomy, relates to the way in which inhabitants of the area source food. That is, 100% local, seasonal, foraged, sustainable and with an intrinsic connection to its surroundings. This same approach is emulated by Narisawa with an unmistakable French flair (learnt under French culinary legends, Joël Robuchon, Frédy Girardet, and Paul Bocuse), resulting in an avant-garde, seasonal and sensory menu that transports diners to a lofty, forested mountainside or a misty coastline in the time it takes to take away one course and bring over the next.

Expect to find dishes such as “Soup of the Soil” and “Essence of the Forest” which reflect their landscapes both in terms of ingredients (think poisonous snake broth fished from the waters near Okinawa, or warm sashimi made from Suruga Bay langoustine) and aesthetics.

Geranium - Copenhagen, Denmark

Organic, seasonal and wild Scandinavian ingredients are at the heart of this chic, minimalist eatery, located on the 8th floor of the National Football Stadium with panoramic views of Copenhagen. Helmed by Swedish chef extraordinaire, Rasmus Kofoed, Geranium is renowned for an extensive tasting menu underpinned by creativity, attention to detail and technical skill, which have earnt it three Michelin stars and a reputation as one of the best gastronomic experiences in the country.

Predominantly plant-based, Geranium places particular emphasis on biodynamic products sourced from its farm, Kiselgården, and other farms within Denmark. This alternative agricultural practice consists of a sustainable, holistic approach that champions organic, locally-sourced materials for fertilising and soil conditioning, views the farm as a closed, diversified ecosystem, and often bases farming activities on lunar cycles. Experimentation plays a key part with unusual vegetable varieties or those left to sprout bringing new tastes and textures to an already highly-inventive menu. Remaining parts of the vegetables are used in staff meals whilst leftover trimmings are composted.

Azurmendi - Larrabetzu, Spain

Gastronomic innovation and excellence are synonymous with Spain’s Basque Country, which has the highest per capita concentration of Michelin star restaurants in the world (32 in total!). Eneko Atxa’s Azermendi claims three of these plus a coveted new Green Michelin star, with an impressive list of eco-credentials that span everything from the produce on the restaurant’s menu to the state-of-the-art building in which it’s housed.

Azermendi is deeply connected to its surroundings with Basque ingredients playing the starring role. It works closely with local producers who specialise in one area of produce, boosting the recovery of some products whose cultivation had been abandoned and were on the verge of extinction. It also supports the community with a composting centre for the town and works with the local hospital to develop far better-tasting meals at no higher cost. Its vast cocoon is constructed from glass, local wood, stone, and recycled materials, and features photovoltaic panels, geothermal energy, rainwater recycling, electric vehicle charging, and much more. Since the restaurant’s opening in 2005, it has morphed into a fully-fledged sustainability centre with a bioclimatic building hosting projects such as a hydroponic crops program with local varieties of vegetables in danger of extinction, and a germplasm bank home to more than 400 local seed varieties of vegetables. At 44 years old, Eneko Atxa has established himself as not just one of Spain’s best – if not the best – chefs, but a true pioneer and visionary in the field of sustainability.

Rest - Oslo, Norway

Fine dining on food waste. Doubtful? Rest is here to prove you wrong. Located in the Oslo’s Kvadraturen district, it stands as a rejection of modern consumerism with ingenious chefs, Jimmy Øien, Mads Revheim-Skjolden, and Christopher Christiansen, intent on showing that no great ingredient – however unconventional in shape, size or cut – need be left behind. They work with a strict zero-waste policy and acquire 70-80% of the restaurant’s ingredients from surplus food such as vegetables that have been deemed unsellable due to their unique appearances. Even the plates and ceramics are made from leftover clay!

The result is a highly inventive menu prepared and presented with exceptional flair and creativity, and comes with a Green Michelin star of approval.
