People who come up to you on the street always do it to get money from the tourist, not because they like you. Do not ever go anywhere with anyone you meet on the street. Ever, not even darling young girls who just want to practice english and then go for a coffee. You will be robbed of a lot of money. In fact you should always go to your own hotel room with ladies you meet unless it is a massage place or a sauna.
The easiest and best thing in Shanghai is to go to a sauna. They will make you feel like a king. Try searching this forum for them.
One very good and slightly expensive one is: (Siyuan) MerryLin sauna meaning 3rd floor MerryLin hotel No. 818 Zhangyang Road, Pudong Shanghai 200122. You can get your hotel clerk to write you a taxi note in Chinese.
