Rosemary’s Greenpoint Tavern is quite possibly the last working class bar in the ever gentrified Williamsburg. Located steps away from the Bedford Ave EL stop, this boozing Mecca remains defiantly old school. The interior looks as if an elderly woman’s craft shop puked all over the walls. White Christmas lights and an abundance of plastic flowers create a festive spirit in an otherwise plain room. But the main attraction is the $3.50 32-ounce Styrofoam cups of Budweiser.
