It wasn't there for the filming. They used sets in the studio for filming. The shop was decorated strictly as a promotion, just for this weekend. It'll all be taken down starting tonight. The pillars and facade top with the shop name on it were built and attached, so they just have to fill a few nail holes I guess, but no need to repaint. One thing I'm puzzled by: in various people's online photos, some of them show the shop front as a deep bluish purple, while others show it as a reddish burgundy-purple. I wonder what color it really was.
