14 people were evacuated from the former World Turned Upside Down pub in Old Kent Road on Friday evening when a fire broke out in the basement.
There were no injuries and part of the basement was damaged by fire.
Four fire engines and around 20 firefighters from Dockhead, Peckham, Dowgate and Lambeth fire stations attended the incident.
The brigade was called at 5.50pm and the fire was under control an hour and 20 minutes later.
The cause of the fire is under investigation.
Domino's Pizza opened in 2011 on the ground floor of the former World Turned Upside Down pub.
