In celebration of the launch of the final season of Boardwalk Empire, HBO threw a 1920s-themed gathering in Harlem last week, where tastemakers and influencers got a taste of what life might have been back then. Dubbed “Boardwalk Backroom,” we caught up with actors Michael Kenneth Williams (Chalky White) and Margot Bingham (Daughter Maitland) — each dressed in period attire to keep in the event’s theme — who tell us about the upcoming season, their characters, and more.

The fifth and final season of Boardwalk Empire premiered on Sunday (Sept. 7). New episodes air Sundays at 9 p.m. ET/PT on HBO.
