Grendel's Den

Grendel's Den was a bar and restaurant in Harvard Square in Cambridge, Massachusetts, located at 89 Winthrop Street. The establishment was frequented by both students and professors of Harvard University as well as many others from the Cambridge and Boston area. The name was a reference to Grendel, the antagonist in the Old English epic poem of Beowulf.

The restaurant was perhaps most famous for the lawsuit Larkin v. Grendel's Den, Inc., 459 U.S. 116 (1982), which reached the Supreme Court of the United States in 1982. The suit challenged the Massachusetts state blue law (16C) allowing a religious institution within 500-feet of a liquor license applicant to prevent the issuance. The United States District Court for the District of Massachusetts ruled in favor of Grendel's Den, holding that the law violated the Establishment Clause of the First Amendment. The Supreme Court upheld the ruling of the lower court. [1]

The restaurant was also a favorite of actor and director Ben Affleck, who shot portions of his film The Town (2010) in Grendel's Den.^[1]
