This is one of several board game shops that were operating in Prague in the early 2010's, where I would sometimes find useful teaching materials (I taught English at the time). This one was mostly of interest to an old friend who was travelling with me, so we stopped by to see if they were interested in anything. Pasaz Rokoko is actually connected directly to the complex of tunnels associated with Palac Lucerna, including Pasaz Lucerna, but for some reason is considered to be separate. What is true is that Lucerna is a much larger complex than is obvious from the street. It was actually designed by the architect Vaclav M. Havel (1897-1979), who was the father of future Czech President Vaclav Havel (1936-2011). According to Wikipedia, anyway, Palac Lucerna is still owned by the Havel family, specifically Dagmar Havlova, the younger Vaclav Havel's sister-in-law, rather than widow (they both have the same name).
