DOG N' SUDS
DOG N' SUDS. Dog n' Suds was a midwestern chain of root beer and hot dog drive-in style restaurants with the now rare form of in-car "carhop" delivery service. The chain was created in Champaign, Illinois, by school teachers James Griggs and Don Hamacher. In 2010 licensing rights were owned by TK&C's LLC of Lafayette, Indiana.
In Dubuque, the restaurant on Rhomberg was opened by Harold W. Petsch. The business was a family operation with Harold's wife, Rosemary, and their six sons all helping out. The franchise ran from the mid-1960s to the mid-1970s when the family started its own business, The Rhom-Burger.
The 1966 Dubuque City Directory listed 800 Rhomberg.
