moving to shangai for the weekend of June 27 (Shanghai)

Dear Internation Shangai community,
I will be in Shangai from June 27 till 30, just to visit the city and to have fun.
I would like to know what you suggest to visit, where going out, if you organize some events in that period.
If there is someone available especially to go out Saturday night, it would be great.

looking forward from hearing news from you

With my kind regards

Donatello
