I hadn't heard of that, but I can tell you that the beef filet has recovered, now using the tamarind BBQ sauce that used to make it so perfect. Very yummy!
CG is one of my favorites. It can be a little loud, but either a window seating or one near where you sat provide the best ambiance outside the Monterrey room.. Been a few years since I ate there, so I am glad the new chef has brought it back up to the standard it used to be.
