E very Mad Men fanatic spent the season wondering whether we were about to see Sal Romano return to the fold at Sterling Cooper Draper Pryce. In real life, Bryan Batt, who played the beloved closeted art director for three seasons, is leaving his old apartment behind. Batt, a Broadway veteran (La Cage Aux Folles, Cats, Beauty and the Beast), author (of a mom-and-son memoir, She Ain’t Heavy, She’s My Mother), and interior designer (he and his partner run a New Orleans home-furnishings store called Hazelnut), has put his one-bedroom co-op on East 79th Street, near Second Avenue, up for sale through Prudential Douglas Elliman’s Clif Thorn and Jim Testa. It’s priced at $425,000, and given that both actor and character are extremely dapper (not to mention that home-design business) you will be unsurprised to find out that it’s a pretty refined-looking home, with prewar inclinations rather than mid-century-modern décor. It’s a first-floor unit with a windowed kitchen and a decorative fireplace, and Batt has been there since the late eighties. It’s just time to move on, he explains. For its replacement, he’s looking for something with even higher ceilings: I’m feeling lofty. If only Sal had bought in Soho in 1965.
