KFC Wimbledon branch has closed for maintenance six days after a rat was sighted in the store.
Windows have been covered up with black bin-liners and a sign on the front door says the store is closed for "repair work".
Message to customers at KFC's Wimbledon branch
A KFC spokeswoman said the maintenance work is completely unrelated to last week's rat incident.
She said: "We have temporarily closed the KFC restaurant in Wimbledon to undertake necessary maintenance work to the building.
"We hope to re-open very soon and apologise for any inconvenience caused."
KFC customers have been advised to visit the next closest store in Colliers Wood.
