On Tuesday, I shared my predictions that PrimeKO is set up to become one of the hippest kosher restaurants on the West Side. When I dined there for the grand opening last week, I had the pleasure of chatting with Jamie-Lynn Sigler. The former Sopranos siren has been spotted at all the hottest venues recently, including Century 21. Not only did photogs snap some great shots of her, but she also tweeted about her retail therapy outing, saying, “Shopped @century21 today for a little downtown. Was packed like xmas! Got good stuff mom!” Wonder if one of the colorful handbags she picked up were with mom’s upcoming birthday in mind.
