The outage came on a busy Valentine’s night, affecting business at local restaurants, stores, theaters and other venues.

“We just make the best out of it. We have great locals, great regulars, you know, so they just came out to have a good time. It’s supposed to be Valentine’s anyway right, candle light,” said pub owner Kevin Johnson.

“If you’ve hung out in Huntington Beach very often, the pandemonium was really kind of on the mellow side,” another man said.
