After 46 years of serving spaghetti and spumoni on the Seattle Waterfront, Old Spaghetti Factory is closing its doors.

Seattle's Old Spaghetti Factory says December 23 will be its last day. That means fans of OSF have less than two months to get their fill of spaghetti with mizithra cheese or baked lasagna served in a historic trolley.

The Old Spaghetti Factory opened on Elliot Avenue back in 1970. It was the second Old Spaghetti Factory to open, after the first one in Portland.

Developers bought the building in July of last year. The Seattle Times reports the purchase price was $9 million.

The restaurant stayed open for the past year and a half as developers worked on ideas.

The warehouse building at the site will be part of the new development plans, as it is designated as a Seattle Landmark.

The Ainsworth & Dunn Warehouse was built in 1902. According to Seattle's Landmarks Preservation Board, prior to housing the Old Spaghetti Factory it served as a warehouse for Frederick & Nelson’s Department Store, a waterproof glue manufacture and a kitchen appliance warehouse.

There are currently no plans to open a new Old Spagehtti Factory in Seattle but the company says it hasn't ruled out the idea.

For now, Seattle fans of the Old Spaghetti Factory will need to travel to Lynnwood, Tukwila or Tacoma to get their fix.
