The White Cliff’s Restaurant & Function Hall on Route 20 in Northborough is on the market for $2 million. The 128-year-old mansion was originally owned by the Wesson family of gun fame. In recent years, it was run as a restaurant by the Tomaiolo family, which has owned several restaurants in the Worcester area, including the Parkway Diner. Family members still run A.J. Tomaiolo’s, also in Northborough. The mansion is almost 20,000 square feet. It has 32 rooms and 17 fireplaces and was built as a summer home.
