The owners of Roustabout, the Italian-American restaurant at 59 Washington Ave., announced Monday evening that it had served its last plate of pasta.

Owners Anders Tallberg and Kit Paschal, who opened the restaurant in 2015, posted a statement about the closing on the restaurant’s Facebook page.

“The past fifteen months have been filled with challenges, excitement and reward. We consider ourselves fortunate to be part the vibrant restaurant community in Portland Maine,” the statement said. “However, it is with deep disappointment that after dinner service on Sunday January 8th, we have closed our doors for good.”

The note did not say why they were closing, and Tallberg and Paschal did not answer their phones Monday night. Roustabout had 75 seats and an 18-seat bar.
