The 40-cover site opened in Islington in early March and boasted a menu developed by television chef James Tanner and Francesco di Marzio, former executive chef at London’s two-Michelin-starred The Greenhouse restaurant.
But it looks to be shutting its doors this weekend after struggling with low footfall.
A post across X-Upper’s social media pages on 30 April says: “I regret to inform you that X-Upper will most likely be shutting down at the end of this week (Saturday). We have had some great customer reviews and feedback since opening but unfortunately we have struggled to get enough new customers to try us for our investors to continue supporting us. It’s been an incredible pleasure to have hosted you, and served you our artisanal sausages.
“Please pass by again before 5 May if you can as we’d love to have you again for lunch/dinner. Big thanks again to everyone who supported us.”
X-Upper’s menu includes sausages and bread priced between £7.75 and £8.75, available to eat-in or takeaway, and a £26 sausage sharing platter.
