A new St. Patrick's themed pop-up bar has just opened in Rittenhouse Square and this is the first weekend it's open.  KYW Newsradio's Hadas Kuznits chats with restaurateur Rob Wasserman about Lucky's Charm, which will be open until March 22nd. They discuss the holiday-themed snacks, Instagramable decor and what it takes to convert a spa into a bar in the matter of a week.
