In an Instagram post, Overington, who opened the restaurant with his partner Victoria back in 2014 when he was just 26 years old, confirmed that the last service would be on Saturday 26 November.
"This has been an incredibly difficult and emotional decision for us, but it is time to close the door on this chapter and start a fresh adventure," Overington wrote.
"We have achieved such a huge amount in our small restaurant; far more than we could ever have imagined or hoped for. For that, Cochon will forever hold a special place in our lives."
Currently ranked number 94 on the Estrella Damm National Restaurant Awards top 100 list, Le Cochon Aveugle serves two ‘blind’ tasting menus (Cochon Aveugle is French for ‘blind pig’) with guests discovering what they are eating when the dishes arrive.
The cooking is grounded in classical French technique, informed by Overington's training at Le Cordon Bleu in Paris, with the wine list, curated by Victoria, focused on organic and natural labels.
"We would like to thank our talented and dedicated staff, both past and present, our incredible suppliers and, of course, our loyal and supportive guests," Overington continued.
"Thank you for inspiring us, pushing us to be better, being there during all the ups and downs and, mostly, for sharing the experience with us and being a part of our Cochon story.
"The food, service and dining experience that our team are creating is truly special and we really believe that we have never been better. These last few months will be a celebration of an amazing eight years and of all that this restaurant has become.
"We hope that we can look forward to welcoming both new and familiar faces to enjoy the Cochon experience one last time before we say goodbye."
Le Cochon Aveugle's sister restaurant Cave du Cochon, which features a more casual offering that focuses on pizza and wine, will continue to operate.
