Restaurants at The O2 are unable to serve food after the mains gas was shut off following a fire at a nearby development.
There are no scheduled events at the north Greenwich venue for Wednesday, September 16, however, a spokesman for the venue said it could not confirm when the supply will be restored.
The cut in gas is due to a fire which broke out at a 22-storey block under construction in Millennium Way in Greenwich affecting a gas main outside.
No-one was injured in the blaze, but the fire spread to a ground floor gas intake room, which has been destroyed.
Six fire engines and 30 firefighters were at the scene from East Greenwich, Plaistow, Deptford, Poplar and Lee Green fire stations.
The brigade was called at 10.38am and the fire was under control by 12.31pm. The cause of the fire is under investigation.
A spokesman for The O2 said: "Due to a small fire at an apartment building construction site next to The O2 this afternoon, the gas supply to the northern Greenwich peninsula has been affected.
"Gas engineers are on site and are attempting to restore supplies. Unfortunately we have not been given a definitive time as to when these are likely to be up and running. We are liaising with the gas suppliers, construction team and our tenants and partners on the peninsula to keep them informed."
