An early-morning fire at a Sarnia restaurant Wednesday caused $400,000 in damage.

Sarnia firefighers were called to Daysbreak Family Restaurant at 293 East St. S. about 3 a.m.

Fire crews from three stations were able to quickly contain the fire to the front portion of the restaurant, but there was heat and smoke damage to the rest of the building.

Nobody was injured in the fire, which is under investigation by fire and police personnel.

The cause of the blaze has not been determined.
