Hello,Mr Schmulty:

Tks for searching the info about Jiaxing,as a resident here ,i am pleased and honor to answer some of your questions:
1.I think it is a safe city ,at least i stay here 26 years ,feel it is safe ,even when walking outside at mid night it is ok.but still be careful when night time if alone!
If u want to visit here ,it is a good choice to visiting sightseeing area and some business market(sweaters&leather&fur and others)

Many restaurants here ,different types ,just depends on what u like.and for entertainment ,there is Karaokay ,musican bar,tea house...

If with a lasy here ,then some romantic restaurant,or maybe can walking in Wuzhen(water villiage),will be perfect!

Anyway ,welcome to Jixiang ,i just show some of my oppinions ,for your info
