Unless porcelan dolls are your thing...
First off, this isn't the easist place to visit. I think we took the metro out to it (at least two changes) and then a decent walk from the stop. We had a tour (in english) of the work areas and it was neat to see the way they formed each individual flower on the statues. They had a neat museum of all the retired and special ones they have done over the years. Around the factory, there are several shops that sell the "as is" ones, where the color is off, or a piece is missing. Things only a professional would notice but you get it for cheap. Unless porcelan dolls are your things its not really worth the trip way out of the city.
