Izakaya is a traditional Japanese drinking establishment where visitors can gather in the evenings, order variety of food and snacks, and spend time having a pleasant conversation. The name Matsu comes from the pine tree as a link to an inalienable symbol of the Kaliningrad region, for if there were no pine trees, there would be no amber and as a consequence no ‘amber land’. Furthermore, the Japanese pine tree symbolises longevity, courage, and resilience. The second part of the concept is the Roku Bar, which translates from Japanese as number 6, one of the three numbers of happiness.
