While Chung's was indeed a cherished institution on Cass, there was a small but excellent Cantonese restaurant on Second, a few blocks north of the Fisher Building, called the China Doll, in a house which had an addition built out to the lot line. I went there through the mid-seventies but moved from the area in '77. I looked for it years later to no avail. Much New Center business in the daytime and from the many apartments north of the blvd. evenings and weekends.
