And now she has a new neighborhood pub: Sea Hag.

Kari Kuelzer, 53, lives in the Cambridge house she grew up in — convenient, since she also runs Grendel’s Den in Harvard Square, her second home since her parents started it in 1971.
She’s been well-known around the neighborhood for decades and even grew up doing theater with Matt Damon in his breakdancing days. In fact, Kuelzer enjoyed a show-biz stint in Los Angeles, too. But, unlike her famous classmate, she returned home to become known on a smaller stage. Now she’s in charge at Grendel’s (with some serving help from her college-age son, another Rindge graduate).
A few weeks ago, she branched out with another cozy pub down the street, Sea Hag. For those who aren’t literary scholars: Both names are nods to “Beowulf.” Her late mom christened the original, and Sea Hag is Kuelzer’s tribute to her.
