The popular East Sacramento business "Crepes and Burgers" was intentionally set on fire Monday morning, according to Sacramento Fire Department spokesperson Roberto Padilla.
Padilla says he can't comment on how investigators know the fire on 56th and H Streets was arson, but he says it was obvious.
The fire started around midnight, and within minutes, the inside of the building was gutted, blackened and charred.
Also, a water main broke across the street after the fire was put out, just before 2 a.m., according to Padilla.
He is unsure if that was related to their firefight.
Nearby businesses in the area are expected to open later Monday.
A firewall kept the flames from spreading to other businesses. No one was injured in the overnight fire.
