Toni Kostian is the sole owner and executive chef of Restaurant Grön in Helsinki, a pioneering destination for contemporary Nordic cuisine. He rose to national prominence after being named Finland’s Chef of the Year in 2016 and has since become a leading voice in sustainable, produce-driven cooking. 

Since opening Grön in 2015, the restaurant has been repeatedly voted Finland’s Best Restaurant and has earned top distinctions from international dining guides, as well as major sustainability awards recognising its ethical and environmentally responsible approach. Kostian’s cuisine is rooted in seasonality, with a strong focus on organic farming, wild foraging, and respectful sourcing. He oversees the Grön Garden in Sipoo, which supplies the kitchen with herbs, flowers, and vegetables throughout the year, reinforcing a close connection between land and plate. 

Beyond the restaurant, he is actively involved in mentoring young chefs and promoting sustainable practices within the Finnish food community. Known for his precision, restraint, and deep respect for nature, Toni Kostian continues to shape a distinctly modern Nordic culinary identity.
