At least five buildings, including the Hong Kong Lounge II restaurant, caught fire.

The fire department ordered the evacuation of a one-square block area, while PG&E crews worked to shut off the gas.

"It's complicated what they have to do, get into the street and shut that down, while keeping their workers safe, it's really a third alarm, that's what it is at this point," said SF Fire Chief Joanne Hayes White.

It took about two hours and 20 minutes to turn off the gas and then fire went out.
