On Wednesday, July 30th, people in the palaces of Marrakech and across Morocco will celebrate the Feast of the Throne in honor of King Mohammed VI's ascension. Here in Boston, the seductive Tangierino gets in on the festivities with a sumptuous wine-paired three-course menu that features rich Moroccan spices in dishes like seven vegetable couscous, wild salmon tangine and an array of exotic sorbets (5:30–10:30 PM; $69 per person; $87 with wine pairing; 617-242-6009).
