You and your friends may start the evening in Capitol Hill -- but once you walk through the doors of Mamounia you're instantly transported to a Sultan's lair, enveloped in richly embroidered pillows and tapestries, the scent of cinnamon and citrus-infused tagines beckoning. Moroccan cuisine is all about combining sweet and savory, and the modestly-priced list of entrees offers a nice variety of couscous, brouchettes and tagines. You can't go wrong with some of Mamounia's generous house martinis and appetizers, best enjoyed while a bellydancer practices her centuries-old art.
