Lewis Barker is executive chef at Terre, the two-Michelin-starred restaurant at Castlemartyr Resort in County Cork, Ireland.
He took over the kitchen on October 1, 2025, succeeding Vincent Crepel, who had led Terre since it opened in September 2022.
Terre won its first Michelin star within six months of opening, then added a second the following year, making it one of only a handful of two-Michelin-starred restaurants in Ireland.
Lewis presented his first menu on November 20, 2025, and went on to retain both stars at his first Michelin Guide Great Britain & Ireland ceremony as head chef, held in Dublin in February 2026.
Early career and background
Lewis is originally from Leeds, West Yorkshire.
He started working in kitchens at 15, taking a weekend job at the fine dining restaurant Anthony’s while still at school, learning the fundamentals of seasoning and flavour under chef Anthony Flynn.
He has said his interest in cooking began in front of the television, citing Saturday Kitchen and Great British Menu as early influences.
Lewis studied professional cookery at Leeds City College, then spent several years working at home before heading to Australia, where he worked at Vue de Monde in Melbourne, under Shannon Bennett, and Quay in Sydney, under Peter Gilmore. Both hold three hats under Australia’s Good Food Guide, the country’s rough equivalent of three Michelin stars.
A year working in Barcelona followed before Lewis moved to Singapore in 2016, where he would spend close to a decade.
There, he worked under Irish chef Andrew Walsh, taking a sous chef role at the Michelin-starred Bacchanalia, and at Vianney Massot, where he was part of the team that won a Michelin star within six months of opening.
In early 2021, at 27, Lewis opened his own restaurant, Sommer, and won a Michelin star within six months, becoming the youngest chef in Singapore to hold one. Sommer ran until it closed in October 2024.
