Investigations are underway into fires at two Italian restaurants in Melbourne's northwest that started within minutes of each other.
The first blaze broke out at a La Porchetta on the Melton Highway in Taylor's Lakes about 2.45am on Wednesday.
Flames quickly ripped through the building, scattering debris throughout the restaurant and leaving the shopfront charred.
Just minutes later, another fire started at Negroni 888 on Mount Alexander Road in Essendon.

Smoke billowed over the area but firefighters contained the fire to a small section of the venue and stopped it from spreading to a nearby car wash.
No one was inside either restaurant at the time and both were severely damaged by the flames.
Officers have not revealed if they are believed to be linked.Â
Both restaurants have been taped off and deemed a crime scene as detectives work to establish the cause of the fires.
