Backstage is among the latest players in the capital’s growing music divide. Hidden among the small shops that line the quay between Cafe Fresco and Costa Coffee, the narrow music bar plays danceable European-edged techno during the week and hosts live DJ sessions most weekends. The interiors are first-class, with floor-to-ceiling mirrors giving the smallish room the feel of a much larger venue. Unfinished concrete walls and metal-and-pine furniture accented with black cushions give Backstage a smart, relaxed feel, much more private dressing room than public storage area. And the menu, which offers Prosecco by the glass ($5.50) and Moet & Chandon by the bottle ($90), definitely says this is no place for poorly dressed road crew or beer-chuggers. Backstage, #377 Sisowath Quay.
