Eight fire engines and around 60 firefighters have been called to a fire at a restaurant on Great West Road in Hounslow.
Around half of the roof is alight.
Two of the Brigade’s 32-metre turntable ladders have been deployed to the scene to help fight the fire from above.
Control Officers took the first of two calls at 1523 and have mobilised crews from Heston, Southall, Heathrow and surrounding fire stations to the scene.
The cause of the fire is not yet known.
