The sales price was $7.2 million, according to Suffolk Registry of Deeds records.

The property is divided into three retail spaces, two of which are occupied by Legal Crossing restaurant and Caffe Nero. The third 1,600-square-foot storefront is available for lease.

“We are thrilled to have purchased this great retail condo in the groundbreaking new Millennium Place development, expanding our interest in the resurgence of Downtown Crossing,” Aubrey Cannuscio, partner of acquisitions for Linear Retail, said in a statement.
