But this February has been so cold that the restaurant scrambled to set up extra heaters outside the Craftsman-style house to keep diners and workers warm during the record-setting cold winter.

"We had three heaters going for a while and this month it just hasn't been enough," said Sam Yoo, a manager at the restaurant. "I'm trying to have the waiters and hostesses wear warmer clothing, but I have one heater set up right by the host stand so they don't catch colds."

For the first time since forecasters began recording data — at least 132 years — the mercury did not reach 70 degrees in downtown Los Angeles for the entire month of February.

The average high for the month was 61 degrees, significantly lower than the historical average of 68 for February. That makes it the eighth-coldest February on record, said Ryan Kittell, a meteorologist with the National Weather Service in Oxnard.
