5. Ryan Chetiyawardana AKA Mr Lyan — Founder of 2018's best bar in the world

One of the most influential bartenders in the world, Ryan Chetiyawardana, better known as Mr Lyan, was the brains behind the official best bar in the world for 2018, Dandelyan.

Originally starting with London bar White Lyan in 2013, the first cocktail bar in the world to use no perishables (including no fruit or ice), Mr Lyan continues to focus on sustainability and waste reduction while keeping drinks innovative and delicious — and it seems to be paying off, as award after award keep coming his way.

Things never get boring, either — in April, he launched all-day cocktail bar Super Lyan in Amsterdam's Kimpton De Witt hotel, Lyan's first venture outside the UK. Meanwhile, earlier this year the award-winning Dandelyan shut down and reopened as cocktail spot Lyaness — and the reception has been just as warm.
