The basement of the Rathaus houses a Rathskeller. The house also includes a rathskeller in the basement that served as a speakeasy. A dimly-lit, gritty establishment, the Rathskeller was considered the "granddaddy" of Boston rock venues. The Stompers played in Boston-area bars such as The Rathskeller and Jonathan Swift's. Rathskeller restaurant is located in the basement space. The three adjoining basements formed a large Rathskeller (dining room) and kitchen. His final show was on May 14, 1976 at the Rathskeller in Boston. Today the Rathskeller is used for occasional private events. The Rathskeller directly connects the ground floor to the Terrace outside. By 1939 it became the German-American Rathskeller, and then Joe King's Rathskeller. In February 1866, he founded the "Kernan Enterprises," a combination hotel and rathskeller. Currently, the Rathskeller is home to a cafe serving legislators and the public.
