The incident occurred at around 4:30 a.m. Tuesday morning.
The robbers were dropped off by a white SUV, possibly a Range Rover, according to the owner, before video catches the robbers chainsawing open the door and then walking through the restaurant to the cash register.
The pair got away with an undisclosed amount of money.
The owners say they are frustrated because the robbery will hurt even more at a time when they are dealing with rising costs.
The restaurant had suffered setbacks before. Its current location opened in February 2019 after a fire burned down their old location in December 2018.
Anyone with information is asked to call the Los Angeles Police Department.
