Modrá myš, which was originally housed in the building of today's Stara Arena (Old Arena) on Masaryk Square, was a place where, in addition to quality drinking, people also enjoyed the company of women. Maybe that's why the company operated only briefly in the years 1920-1925. 86 years later (2011), bartender Radim Hamrosi decided to open a bar, which would be an oasis of calm on the busy Stodolní Street and the quality of drinks would continue the First Republic tradition. He created famous cocktails, which surpassed time and ideas, until 2019, when the company took over a new team. The new operators are now continuing not only the era of the original Blaue Maus, but also the creativity of Radim Hamrosi. Drinks in the current menu refer to the famous Ostrava villas and thus remind locals and tourists of the rich history of the city.
