Police said the men cut a hole in the roof of the Speedy Cash check-cashing business and made their way inside around 7:30 a.m. Saturday.
Employees were inside the shop at the time and ran out of the building.
The suspects fled through the back door and drove away in a dark SUV.
Investigators said this may not be the first time these men have tried to rob an Anaheim business.
"Several months ago near Beach and Ball Road, there was another robbery in which the method of entry is very similar. Our officers are here investigating possible connections if any at this time," said Anaheim Police Department Sgt. Bob Dunn.
Investigators said the check-cashing business was not robbed, but one employee claims her purse is missing.
