Magerman spoke to Waltham Patch after recent reports from Five Guys' corporate office that the project had been delayed.
"I [am] trying to open between the middle and the end of October," Magerman told Waltham Patch. "We're moving forward as we always were."
The store will be located the new 1030 Main St. plaza named "Main Street Marketplace."
Magerman said he does not have an exact opening date yet but does not expect to encounter any future delays.
