Sebastian Guilleminault, General Manager

Growing up in small village in Dreux, France, taking an apprenticeship in Catering & Hotel Management within a Michelin-starred restaurant on the Champs Elysees was quite a learning curve for Sebastien.  

Mentored by some of the very best in the industry, Sebastien quickly shot up the ranks to Assisting Managing Director, before leaving everything behind for London in 2006. On arrival in London, Sebastien secured a position and training with Galvin at Windows, before moving onto Restaurant Manager positions in other London restaurants.

Sebastien joined ZOILO in 2013, and over the last four years he has moved from a Restaurant Manager position to Operations, allowing Diego the opportunity to spend more time in the kitchen.

Gian Mario, hEAD Chef

Gian was born and raised in Sardinia, but moved to the UK in 2005 in search of opportunities to break into the food & drink industry. He always knew he wanted to be a chef, and kept his mind on that goal when starting out as a kitchen porter in a gastro pub.
