Born in Greece, his family moved to Singapore when he was 10 months old. His father, Hugh, 63, runs the Asian master franchise for the O'Briens Irish Sandwich Cafe chain here. When he was 16, Mr Hoyes-Cock moved to the UK to attend Eton College and read law at Bristol University.
One of his earliest memories of food is of family meals at Samy's Curry Restaurant here when he was four. "I always have the mutton biryani, fishcakes, chicken tikka and rice with fish curry on a banana leaf."
At work, Mr Hoyes-Cock is also used to turning up the heat with The Podium Lounge, a high-octane ultra lounge party. The annual post-F1 race extravaganza at The Ritz-Carlton, Millenia Singapore is jam-packed with music performances, fashion and art shows, and lots of booze.
Headlining this year's party, which takes place from Sept 15 to 17, is Grammy Award-winning R&B star Macy Gray and rapper Coolio from the United States.
Mr Hoyes-Cock started organising monthly high-end parties in 2005 and was invited to host a three-day F1 party in 2009, which evolved into The Podium Lounge.
He checks out parties and cocktail bars around the world once every two months. But he has cut down on his travelling and spends his holidays with his homemaker wife, Anna, 35, and their three children, aged five, three and 10 months.
He says: "You need to constantly reinvent yourself as you are only as good as your last party."
What is the biggest thrill of organising parties?
You never know who is going to show up at the very last minute. Gordon Ramsay (British celebrity chef) was mobbed when he showed up at The Podium Lounge in 2014. Kim Kardashian (American reality TV star) also turned up with her large entourage in the Abu Dhabi edition that year.
What is a memorable party that you have attended?
A New Year's Eve beach party at Amanpuri Resort in Phuket. It had a very luxurious and intimate vibe with fewer than 100 people. I mingled with guests such as (former Spice Girl) Mel B and Japanese fashion designer Kenzo Takada, who came in Speedos, a fishnet top and feathers.
