Alberto Landgraf was born in Cornélio Procópio, a small town in the Brazilian state of Paraná, into a family of German and Japanese descent, according to a biography published by Reporter Gourmet. That dual heritage would later become the defining thread of his cooking, with critics repeatedly pointing to the way he layers Japanese restraint and precision onto Brazilian ingredients. He did not set out to become a chef. Landgraf initially trained in physics, and it was only after he relocated to London in the early 2000s, ostensibly to study English, that he found his way into professional kitchens, a detour that changed the course of his career entirely, the same profile notes.

Once in London, Landgraf immersed himself in the city’s fine-dining scene, training at Westminster Kingsway College and working in the kitchens of Gordon Ramsay and Tom Aikens, two of the most demanding names in British haute cuisine at the time, according to FOUR Magazine. He also spent time working with the French chef Pierre Gagnaire, broadening his technical grounding beyond the British kitchens where he started. Landgraf returned to Brazil in 2006 carrying that European training with him, and two years later, in 2008, he opened his first restaurant, Epice, in São Paulo, betting that the precision he had learned abroad could be applied to Brazilian ingredients back home.

Epice quickly established Landgraf as one of Brazil’s most closely watched young chefs, earning a Michelin star and being named a “South American rising star” by FOUR Magazine, cementing his reputation years before Oteque existed. He ran Epice for seven years before closing it in 2015, a decision that came during a period when he was also processing the death of his mother, according to the same FOUR Magazine profile. Landgraf stepped back from the industry to regroup rather than immediately opening something new, and it was three years later, in 2018, that he opened Oteque in Rio de Janeiro, a considerably more personal restaurant built around his Japanese heritage and a stripped-back philosophy of “simplicity and technical precision rather than ingredients,” as described in a profile by Culture Trip.

Oteque’s rise was fast by Michelin standards. The restaurant earned its first star not long after opening, and by 2020 it had been awarded a second Michelin star as part of that year’s Rio de Janeiro and São Paulo selection, according to the Michelin Guide’s own announcement, making Landgraf one of a small handful of Brazilian chefs to hold two stars at once. Oteque has also placed consistently on the global rankings that matter most in fine dining, landing at number 37 on the World’s 50 Best Restaurants list in 2024 and ranking 38th on Latin America’s 50 Best Restaurants in 2025, keeping the restaurant inside the region’s top tier for several years running rather than as a one-off entry.

Landgraf’s profile has grown well beyond Brazil’s borders through international press coverage and guest appearances rather than any single breakout media moment. He has been profiled by outlets including Tatler Asia, FOUR Magazine and Culture Trip, and has appeared as a speaker at industry gatherings such as the Food on the Edge symposium in Ireland and the European Food Summit. In August 2023 he took his cooking abroad for a high-profile residency, taking over the Sabayon kitchen at EQ Kuala Lumpur for two weeks to present a menu fusing Brazilian ingredients with Japanese technique to a Southeast Asian audience, according to Tatler Asia. The residency was covered widely across Malaysian and Singaporean lifestyle press, extending his recognition into a region where Oteque itself has no physical presence.

Landgraf keeps a noticeably lower commercial profile than many chefs with comparable Michelin standing, and no major long-term brand endorsement or sponsorship deal turns up in available reporting. What functions closest to a commercial partnership in his career is guest chef work, most visibly the paid residency at EQ Kuala Lumpur’s Sabayon restaurant in 2023, where the hotel built an entire marketing push around his two-week takeover, as covered by The Edge Malaysia. These appearances function more as reputational cross-promotion between his restaurant and an international hospitality partner than as a conventional product endorsement, and there is no public record of him lending his name to a packaged food line, cookware brand or spirits label in the way some peer chefs have.

Unlike many chefs of his stature, Landgraf has not built a restaurant group. His commercial footprint centers on Oteque itself, run as a single, tightly controlled dining room rather than a multi-location brand, following the earlier, now-closed Epice in São Paulo. His main venture beyond the restaurant is publishing: in 2026, Phaidon released his debut chef monograph, “Oteque: Ideas, Principles, Recipes, Stories and Connections,” featuring essays by food writer Andrea Petrini alongside recipes and photography documenting the restaurant, according to Phaidon’s own announcement. The book is notable for a detail that doubles as a business collaboration in its own right: working with the sustainability consultancy Reach Eat, Landgraf calculated and published the carbon footprint of all 78 dishes in the book, a step The Upcoming reported as a world first for a chef cookbook.

There is no reliable public record of personal real estate or other major assets held by Landgraf outside his restaurant business. What is documented is the property Oteque itself occupies: a house built in 1938 in Rio de Janeiro’s Botafogo neighborhood, which Landgraf had painstakingly refurbished into the restaurant’s current form, an open-plan kitchen and dining room built around exposed brick, a handful of tables and a separate six-seat chef’s counter, according to Brazil City Guides. That renovation represents a meaningful, self-directed investment in a single physical space, but whether Landgraf owns the building outright or operates it under a commercial lease has not been disclosed, and no filings or reporting establish it as a personal asset separate from the restaurant business itself.
