If you want to give your credit card some exercise, head out to Tianzifang in Huangpu. Splash some more cash at Huai Hai Road Shopping District, Xintiandi Style Shopping Centre, and Taikang Road.
If you're planning a bit of sightseeing head to Former French Concession— just one of the monuments in Huangpu. Why not live the cultural experience and visit the art galleries and museums in the area— your sightseeing tour starts here. Shanghai has other landmarks you might want to visit such as The Bund.
