Chan’s Chinese Restaurant on Southeast Third Street in Bend sustained serious damage in a fire that tore through the building early Friday morning.

Firefighters were called to the restaurant around 2 a.m. on Friday, according to a news release from the Bend Fire Department. When crews arrived at the scene, they found that the attic above the kitchen was filled with smoke and still burning. They were able to put out the blaze within an hour, but heat and smoke caused about $700,000 in damage.

Officials believe the fire started in the kitchen, but are still investigating.

Lap Chan, the restaurant’s owner, said on Friday evening that it could be three months before the restaurant is ready to reopen.
