The restaurant was opened in a former Lyon’s Tea House in Smithfield by Toulouse-born chef Pascal Aussignac and his business partner Vincent Labeyrie in 1998.
It won a Michelin-star in 2002 for its ‘French tapas’ style of dining, which encourages diners to order between three and five small plates.
But the site is closing after dinner service tonight before relaunching this autumn with a new design and concept.
A representative for the restaurant was unable to confirm whether the small-plates will be staying, but says further information on the revamp will be released soon.
“I am committed to restoring the restaurant to its original beauty, ensuring that it retains its rightful place as one of the best and finest restaurants in the country,” says Aussignac.
“This is such an exciting development and I cannot wait to share the updated look and the new concept with [everyone].”
Club Gascon is part of Aussignac and Labeyrie's Gascon Connection Restaurants group portfolio, which also includes Duck’N Roll in Leeds and London's Club Gascon/Le Bar, Comptoir Gascon, CIGALON/Baranis, and Chip & Fish.
