Caldesi in Belsize closed at the tail end of last month having only launched in April last year.
A statement on the restaurant’s Instagram page said: “We have officially closed our doors at Caldesi in Belsize and are deeply grateful for the support and cherished moments shared with our guests.”
No reason was given for the closure.
Caldesi in Belsize took over the site of long-standing Italian restaurant Calici and joined Caldesi in Marylebone and the more high-end Caldesi in Campagna, Bray.
The restaurant had 100 covers and – in a departure for the group – majored on dishes designed to be shared.
Originally from Tuscany, Caldesi launched his first UK restaurant in 2002 on Marylebone Lane, following up with Caldesi In Campagna in 2007.
He and his wife Katie have published numerous cookbooks and also featured in the BBC2 series Return to Tuscany.
Both Caldesi in Marylebone and Caldesi in Campagna continue to operate.
The group also operates the La Cucina Caldesi Cookery School, which also has sites in London and Bray.
