There are some restaurants that do not sign up to any particular regional cuisine. The food world is their oyster and their international menus are not constrained by any rules. Many fine dining restaurants would fall into this category.
Think East meets West, Arabic cuisine mixed with local food, a potpourri of foods from the three continents bordering the Mediterranean, a French inspired starter followed by an Argentinean prime fillet or an Indian spicy dish. Each restaurant will follow its own philosophy and vie for your attention.
