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.
