Firefighters had to battle a blaze at Cazuelas Grill on North High Street on Wednesday.
The fire was reported around 4:30 p.m. at the Mexican restaurant which is a couple of blocks north of Lane Avenue.
Images from Chopper 10 showed firefighters had the blaze under control quickly, but they were using chainsaws to cut into the side of the building.
The restaurant was closed at the time, and no injuries were reported.
Officials say the fire was started by a worker trying to heat up frozen pipes.
High Street was blocked by fire equipment while firefighters were at the scene.
