Sam Chin opened the Dan Chan Restaurant in 1964, with help from his father, Frank.
The building was a new construction and part of the build-out of the John Fitch shopping center.
In 1975, Sam sold Dan Chan to create a larger much nicer restaurant on the Fitchburg/Leominster line - "Singapore" which featured a large bar and lounge as well as the restaurant.
A fire claimed Dan Chan's on December 26, 1996 and the Fitchburg Singapore stayed open until 2020 when it closed during the Covid crisis. The Singapore opened again briefly for 3 more years and then closed again on June 14th, 2025.
