Travel / Starbucks in Wawel Castle, Krakow. Is this a joke or true? [42]

Hi guys,
I've heard rumors that Krakow has their first Starbucks open in the Wawel Castle, yeah inside the castle territory (krakow post/article/1979) Can someone tell me is this true or just a joke, since if you see the post date is on the April's Fool.

Thought anyone?
