staying at putuo for 3 days, any recommended shanghainese restaurant?

Well, in my impression, there is no special Shanghai resturant in this area. But the favor of many local restaurants is similiar to authentic Shanghai cuisine.
I remember that the restaurant of Citic Putuo Hotel provides good taste Shanghai cuisine. You can try it. The address is No. 22, Jinsha Road, Putuo District.

Hope you like. :-)
