|99 Broadway - Boston (August 2009)|
Location: 99 1/2 Broadway, Boston, Massachusetts, USA
The only reference I have found to the Empty Barrel being a former lesbian place is this short mention by Michael Bronski. This is part of an article outlining a LGBT walking tour of Boston:
Near Jacques (on Broadway) was the Empty Barrel (99 ½ Broadway)—for many years a speakeasy frequented by lesbians. Visitors can still see the stairs leading down to the entrance of the basement bar.
I'm sure more could be found out by hitting the paper archives. Yet another thing to add to that never ending "to do" list.....
