Rub23 is an Icelandic restaurant that uses ingredients from Icelandic fishermen and farmers. Ingenuity from Asia and America. We specialize in seafood and have a wide variety of fish species and a wide selection of sushi dishes mixed with steaks and desserts. What makes the restaurant unique both in Iceland and internationally is the varied way in which the menu is put together, including homemade spice mixtures that customers can choose from, the so-called RUB. RUB has become a well known term for spice mixtures that are either put onto or rubbed into food, as the name indicates. The customer can first choose a particular ingredient, for example a special type of fish or meat and then choose from a list of spice mixtures those he wishes to try. On the menu one can find favorite combinations of the chefs.
