Shanghai is huge and if shopping is your cup of tea, I suggest you visit "Chee Pu Loo" which is a large shopping area with 4 to 5 large shopping bulidings side by side so you can really virtually shop till you drop and the clothings, leather jackets etc are reasonable in price. Of course you must bargain and walk away if they don't agree with your offer. More often than not, they will drag you back into the shop and agree with your price when you turn to leave the shop. Another way to sight-see by night is to hire a cab from your hotel and ask the driver to take you down all those night markets/street stalls. about 8 years ago
I lived there a lifetime ago and returned 4 years ago to lots of changes! I spent 4 days there revisiting old haunts and discovering new ones. Here's my shortlist:
The Bund, early morning. City wakes up, river is bustling, lovely.
Old French Quarter. Just amble about and explore the old (last?) alleys and shops. Increasingly, there are lots of new boutiques and tea houses. Especially around the Jianguo hotel and huai Hai Lu. Be prepared to be barraged by folks with laminated cards showing you all the watches and brand hand bags they have for sale in a store nearby. Can get irritating.
For fabric and tailoring, the Shi Liu Fabric markets is interesting. 3 floors of fabrics and vendors of silks, brocades, wool jackets, bed linens, etc, bargain HARD!
Dong Tai 'antique' market. Dubious age of the relics, but a good lark to see.
Zhou enlai & sun yat sen's residences are nice
Tai kang Lu is an area that is full of small boutiques, galleries and cool cafes. Less touristy than Xin Tian Di area- which is still OK. The dumplings house there is fab.
Shanghai museum, and Moganshan Rd for contemporary artists warehouse district.
Have fun! about 8 years ago
