Chef Brendan Cashman confirmed the business, which is located on the ground floor of the Clarion Hotel on Lapps Quay, was being wound up.
Mr Cashman and his wife Carol ran the restaurant together and said it was the right time to move out of Clarion, despite their most successful year to date.
“The couple came to this hard decision, having weighed up their personal and professional aspirations for themselves and their customers, versus what they felt could be delivered by continuing under their current arrangement with the Clarion Hotel.
“While Brendan and Carol are saddened to let go after all the years of hard work and sacrifice, they are very much looking forward to a short break with their young family and are excited at new beginnings and& future projects,” a statement issued on their behalf said.
Augustine’s opened five years ago on Washington Street, and relocated to Lapps Quay in 2009.
This increased the size of the operation from a 45-seat venue to a 140-seater.
During its time, it has been lauded by Michelin, the Restaurants Association of Ireland, Bridgestone, Georgina Campbell and Paulo Taulo for its varying and experimental menu.
Mr Cashman said a special farewell menu will be served on Feb 25 and the chef has encouraged those interested to make a booking.
“It is my personal goal to wow our dinners on my last night cooking in Augustine’s with unforgettable cuisine.”
Prior to establishing Augustine’s, Mr Cashman set up the Douglas Village Food Company in 1997.
