Travel / Złote tarasy in Warsaw [5]

You're both partly right. The VS store is currently under construction in Złote Tarasy. It does not opeate yet, but it says that it'll be soon. The space for it is located on the ground floor near the entrance from Złota Street. It is covered by a pink banner with Candice Swanepoel on it and VS logo.

Life / Wroclaw Stadium and the Queen gig. [20]

Queen = John Deacon, Brian May, Freddie Mercury, Roger Taylor.

If I were him I'd legally threat Brian and Roger for using the name that was a common share of four people.
