Six fire engines were today called to a blaze at 100 Wardour Street, the Soho address of D&D London restaurants Carom and Floridita.
Both venues have temporarily ceased trading as a result, with no fixed date being announced for when they will re-open.
The London Fire Brigade (LFB) reported the incident via its Twitter account after being called to the scene at 11.54 and 35 firefighters were in attendance.
The fire affected a restaurant kitchen on the ground floor as well as a second kitchen in the basement of the building.
Around 20 people were evacuated from the site and there are no reports of any injuries.
The LFB has since stated that the fire has been brought under control with crews from Soho, Lambeth, Kentish Town and Euston fire stations at the scene, damping down the damaged area.
The cause of the fire is not yet known.
D&D London released the following statement: "Due to a fire at 100 Wardour Street Soho, D&D London's Soho venues Carom and Floridita will be closed this weekend.
"The management will be updating all customers through the respective venue websites in due course on when both venues will be re-opening."
