I love TV, but I have to admit I've never heard of this one before. Per Wikipedia, "Kitchen Nightmares or Ramsay's Kitchen Nightmares USA is an American reality television series on the Fox Broadcasting network, in which chef Gordon Ramsay helps failing restaurants." This very second, the show is filming at Mohito on Washington north of Park.
A CH reader reports that she "overheard the staff last night bitching about how Ramsay is changing Mojitos menu, cursing at the staff..."
I haven't heard anythink about them being in dire trouble, but have heard very mixed reviews. My experiences have been mostly good.
