East Williamsburg’s Pine Box Rock Shop has long been a neighborhood darling for many reasons, including its many personal touches (the ticket stub collection on display at the bar) its events (try finding standing room in there during its monthly Vegan Shop-Up), its snacks (the plantain empanadas), its good drinks and good service. As of this past weekend, patrons can experience many of those same charms at a new spot Pine Box owners Jeff and Heather Rush have opened in Bushwick: called Precious Metal, the new spot is a little more grown up, but just as accessible as its sister location.
