The Washington Square Bar & Grill was a landmark restaurant adjoining Washington Square in San Francisco's North Beach neighborhood. Known widely as the Washbag, so named by columnist Herb Caen as a play on words, it was a favorite gathering place for a generation of writers, politicians, musicians, and social elite.
The restaurant was opened in 1973 by local Ed Moose, a former dispatcher and reporter for the St. Louis Post-Dispatch, his wife Mary Etta, and partner Sam Dietsch. Moose organized a softball team, the Lapins Sauvages, composed of famous and influential people who were regular restaurant patrons. Caen often wrote of the team's exploits in his newspaper columns, describing its travels to play in major stadiums in various locations around the world. In 1989 author Ron Fimrite, another of the softball team members, wrote The Square: the Story of a Saloon, describing the restaurant's place in San Francisco's cocktail culture.
