Authorities are investigating two fires that erupted within hours of each other and caused major damage to a popular Long Beach restaurant.
Long Beach Fire Department spokesman Brian Frisk said the first blaze was reported shortly before 9:15 p.m. Sunday and crews got it under control in 11 minutes.
Frisk says a second fire was reported after 1 a.m. Monday.
Frisk says one firefighter was treated at a hospital for minor heated-related injuries.
The Hof's Hut chain has three other locations in California. It traces its origins to a 1940s burger stand.
