From 1986 to 2000, under the ownership of Lou Moench, Father's Office was influential in the rise of America's craft brewing industry and the establishment of smoke-free bars in California.

Yoon opened the bar's kitchen which had previously offered cheese plates and a list of local delivery options for patrons to bring in.

[6] The main attraction was the Office Burger, a patty of fine dry-aged beef topped with caramelized onions, Gruyère and Maytag cheeses, applewood-smoked bacon compote and arugula served on a soft roll.

[7] Sang Yoon is infamous for allowing no substitutions or alterations of any type to the food served at Father's Office, including no ketchup.

[8] A second Father's Office location in the Helms Bakery building in Los Angeles, California was opened in April 2008.
