Yannick Alleno, France
Alleno grew up cooking in cafes around Paris (literally "grew up," he was cooking in kitchens since he was around seven years old). When he turned 15, he trained under some of the greatest chefs in Paris at the time. He earned his first Michelin star in 1999, and then another in 2002. He then moved to open his own restaurant, earning himself two Michelin stars in the process. In 2003, he was awarded his fifth just three years later. Alleno is one of the most decorated chefs of all time.
Claude Bosi, England
Bosi began cooking at a young age in his parent's restaurant. By the time he could leave, he enrolled in a catering college in Lyon, France, and he picked up an apprenticeship that landed him in Paris. He cooked his way through the city for several years before he decided to move back to England and open his own restaurant. In 2000 he opened his first restaurant, Hibiscus, which earned a Michelin star within the same year. He closed down the restaurant to renovate and re-orient his cuisine, and in 2017 he opened Bibendum in the same spot. Lo and behold, that restaurant earned two Michelin stars in its first year in service.
