George began working with the Southern Pacific Railroad as a young man and eventually worked his way up to chef. He had a reputation for being a quick learner and a hard worker. With his many years of experience in food service and his wife's encouragement, he opened Dunlap's Dining Room in 1930. The family continued to live upstairs while the downstairs functioned as the restaurant.
The restaurant became a popular gathering place with middle-class families and state government workers. The family even hosted Earl Warren and Governor Frank Merriam. Dunlap's Dining Room operated from 1930 until Dunlap's retirement in 1968.
In 1997, Audrey Dunlap Wilcox, the Dunlap's daughter, donated the home to the Sacramento Children's Home. Since that time, the home underwent a major renovation and has housed community service programs. It is listed on the National Register of Historic Places.
