No. You must not go, unless you have local friends going with you, either Hangzhou or Xiaoshan. if you don't then, listen,
(1) Same as S333's comment - do not ask Taxi driver or others to go, go to those common and famous one; (2) ask them to have full price list before ordering; (3) do not order drink not being shown in the list / menu; (4) do not let girls ordering drinks, must ask your permission; (5) if you have any problem, call the police, don't be afraid of them. Anyway, Hangzhou is not suitable for travellers. Get a taxi and go to Xiaoshan - 20 mins and costs maximum RMB 50. Xiaoshan doesn't cheat customers.
