Located at 157 Allen Street in Manhattan’s Lower East Side, Copper & Oak, is a serious whiskey and cognac bar. No mixed drinks here, just straight up liquor, hundreds of types (also, three beers and two wines).  Very small space.  Menu is read off of a kindle.  If you’re a fan of amber-colored liquid, you need to include Copper & Oak on your next LES NYC bar crawl sooner rather than later!
