Dark Horse Books is no longer a fixture on the “New U”—and, for that matter, neither is Flying Saucer Discs. Immediately after Thanksgiving, both shops moved to 1604 17th St. NW—the books to the first floor, the discs to the basement. “When Zig-Zag Cafe left, that kinda cut business,” says Dark Horse co-owner Liz Goodwin of her shop’s previous site. Rather than close up permanently, which was a possibility, Goodwin, co-owner Lynne Englert, and new partner Meta Schrenk chose the Dupont Circle location. Already they’ve noticed more walk-by traffic, and the front patio allows them to entice shoppers with an outdoor table of remainders. Dark Horse will continue its emphasis on literary fiction and poetry: “We don’t do best-sellers….Browsers can come in and they’re not overwhelmed [by an immense selection],” Goodwin explains. She, Englert, and Schrenk have also duplicated the former store’s homey atmosphere, with cushy carpeting underfoot, lamplight, and a selective inventory, mostly of trade paperbacks. Almost everything, in fact, appears the same, including the amount of legroom. Space is still limited, and no readings or signings are planned as yet—at least not until the decorating’s finished.
