Dylan was born in Dublin and raised in Belfast. He studied in Portrush Catering College and Belfast Institute. He began his first Job in Jurys Inn, Belfast and then left to work in Roscoffs, Northern Ireland's only Michelin starred restaurant. He also worked at The Commons Restaurant and Peacock Alley with most of his culinary skills being acquired at John Burton Race in L’Ortolan and Tom Aikens in Chelsea where he became Head Chef.

Dylan returned home to Ireland take up his own Head Chef position in Mint restaurant where he received a Michelin star. While in Mint Dylan was the subject of a fly on the wall documentary, Pressure Cooker that created a public awareness in the media of Dylan’s creativity and determination.

People who have worked with Dylan describe him as driven, ambitious, determined, innovative and intense. He is known to be incredibly passionate about his work and has been described by food critics as a "creative genius" and an "incredibly talented chef."

Dylan opened Rustic Stone in August 2010 which is a casual dining, contemporary restaurant that delivers on the flavours Dylan is so passionate about but without the formality he previously would have been associated with. Rustic Stone has been an incredible success and has received excellent reviews from food critics in Ireland!

From Rustic Stone, the Raw menu emerged, which was developed by Dylan keeping his ethos on nutrition and flavour to the fore.

Dylan’s next move is the creation of 2 concepts under one roof on a location on Fade Street. At Fade Street Social by Dylan McGrath he celebrates Irishness aiming to bring us back to some of our tradition as well as embracing the contemporary food influences that have grown in Ireland in the past 30 years.

2011 was the year that returned Dylan to our TV screens with the first series of MasterChef Ireland. The show was a huge hit in the ratings. Alongside old friend and fellow restaurateur Nick Munier, they presented and judged the show to find Ireland’s first MasterChef winner. The second series which is now on air promises to be even better.
