Fashioned out of the shell of a former 19th-century engine warehouse, this cavernous restaurant in one of the landmark features on the docks mid-way between Cais do Sodre and Alcantara. There's an industrial quality to the interior, with the design drawing on the building's history. The menu is international haute cuisine and features dishes like asparagus risotto, deep-water rose shrimps in champagne sauce, and grilled Iberian black pork tenderloin. The arm-long wine list is impressive, with Portuguese labels at the fore. Kais is particularly suited to large groups, but for smaller parties go downstairs to the rustic-styled Adega do Kais, where grilled meats are the speciality.
