The name translates as “Back Pocket,” an apt description for this one-room restaurant tucked into the side of the Royal Opera House. The tiled room is decorated with opera memorabilia, and sometimes you’ll find yourself dining next to tuxedo-clad members of the orchestra between performances. Diners perch at the counter at little tables affixed to the walls or, during the summer, outside in the sun. The food is traditional Swedish cuisine—husmanskost, as it’s known—with particularly good seafood, and best enjoyed with a Swedish beer.
