The Evans Farm Inn, situated on 40 rolling acres along Chain Bridge Road where the Evans family lived for years, is widely known for its rustic atmosphere and picturesque charm.

The "farm" includes several out-buildings, among them a waterwheel and millhouse, and a barn and a cookhouse built of old paving blocks from Georgetown.

A large portion of the restaurant's vegetables come from a greenhouse on the premises. Farm animals roam about the grounds.

The opening of the inn, in 1958, came after Mr. Evans had established himself in Northern Virginia as the operator of Evans Coffee Shop in Arlington. He also had operated Evans Cafeteria in the District.

The coffee shop, which began as a 50-seat operation, opened in 1939 with a $2,000 investment. By the mid-1950s it had expanded to 265 seats.

Its furnishings included a much-admired array of historical memorabilia, including weapons, portraits and tools that predated the Revolution, as well as a collection of items that related to Robert E. Lee.

At the coffee shop, Mr. Evans won a reputation for hiring older workers, handicapped persons and World War II refugees.

Meanwhile he was learning the cafeteria business, working and studying at a number of establishments and chains including the Automat in New York, before finally coming here.

A member of the American Restaurant Magazine's Hall of Fame, Mr. Evans was named Restaurateur of the Year in 1965 by the Restaurant Association of Metropolitan Washington. He held many other honors.

During World War II, he served on the industry advisory committee of the Office of Price Administration and was also attached to the War Production Board and the Office of Price Stabilization.
