The fire brigade was called in the early hours of this morning after smoke was spotted coming out of an old coal chute.
The smoke was spotted at about midnight coming from The Cockney Grub House in High Road, Seven Kings.
Two fire engines arrived on the scene at 12.10am and left at 2.20am to deal with the small electrical fire.
Mark Mills, watch manager, said: “The owner was phoned so he turned up very quickly and we dealt with it before any major damage occurred.”
The restaurant is open for business.
Mr Mills also said in the run up to Christmas people should check their smoke alarms. Free fire alarms and checks can be arranged on www.london-fire.gov.uk.
