From Forgotten NY:
Back in the 1970s, though, this was one of the premier rock venues in Brooklyn, Zappa’s, which for a time was known as the Rock Palace. ... After its conversion to a disco, the hard rock scene in Brooklyn shifted to L’Amour in Bensonhurst in 1981, which packed them in with top metal acts until 2004. By then, the Brooklyn concert scene was shifting again to Williamsburg.
From Tom Watson: My Dirty Life & Times:
Johnny [Thunders] could be a terrific live act — or he might be semi-comatose. I remember having a semi-lucid discussion of Reggie Jackson with him over beers at the old Brooklyn rock factory Zappa's before a scorching set in 1979.
