Duff's Brooklyn is a heavy metal bar located in Williamsburg, Brooklyn (168 Marcy Avenue, between South 5th and Broadway). Duff's initially opened as "Bellevue Bar" in the Hell's Kitchen, Manhattan in 1999, before moving to Brooklyn in 2004 with a name change to Duff's Brooklyn.The original Brooklyn location was at 28 North 3rd Street, where the bar resided from December 2004 to December 2008. Due to the rapid gentrification of area, the bar was forced relocate in December 2008. The bar reopened in December 2008 on Williamsburg's gritty South Side (168 Marcy Avenue), in a space four times larger than the original bar. Duff's is frequented by Tri-state metalheads and rock n' rollers, and is a stop off for many heavy metal bands passing through New York City on tours. Some visitors of note h
