In a statement on social media, the restaurant blamed the current trading environment as well as restrictions on hospitality businesses imposed by the latest budget for the closure.
The restaurant’s final service will be 28 June.
“After much reflection, and as a result of the substantial business rates and National Insurance cost increases imposed on us in this year’s budget, we have decision to close Margot,” it says.
“We are deeply grateful for the support, memories and meals we’ve shared with this wonderful community. Thank you for allowing us to serve you. Your loyalty and encouragement have meant everything to us.
“Though this chapter is ending, we are proud of what we built and will carry these memories with us always.”
The Italian restaurant launched in the summer of 2016 by former Bar Boulud maitre d’ Paulo de Tarso and Nicolas Jaouën, the former manager at La Petite Maison, although they have since parted company.
The restaurant is named after de Tarso’s mother-in-law and uses an image of a Dachshund, which was the affectionate nickname given to her by her husband in reference to her petiteness.
In its description of the restaurant, Michelin says ‘top quality ingredients and bold flavours run throughout’ the menu and points to Margot’s ‘well-chosen wine list’, which it says has a strong focus on the regional wines of Italy.
