Althaus is a Bavarian restaurant in the center of Gdynia, Poland. The restaurant is a traditional Bavarian cuisine, therefore, the atmosphere of southern Germany was exposed subtly using natural materials such as golden oak, bottle green and copper that appears in decorative items such as lamps, mosaics and chandeliers, all that refer to the production of conventional beer. There is a slightly different atmosphere in each room: a combination of calf skins and wood painted white outweighs the ground floor.
