Xujiahui
If you're looking for anything electronic, Xujiahui is the place to start. Pacific Digital Plaza is a huge electronics mall in two parts. Phase 2 exit 10 of the Metro station is more oriented to the end-user market; for things like custom-built computers or parts for do-it-yourself, try the upper floors of Phase 1 exit 9. There are several other electronics vendors in the area, including a Buynow exit 10 or 14 and look up by the footbridge.

Lots of additions to this district, on a seemingly weekly basis. Check out the entire Xujiahui area and Times Square (http://www.shtimessquare....) the latter's on Huaihai Rd for some of the larger malls. Creative boutiques can be found on Julu, Changle, Anfu and Xinle Roads throughout the French Concession, in addition to a high concentration of one-of-a-kind buys for sale in Tian Zi Fang northwest of the Luwan Stadium.
If you are looking for anything electronic, Xujiahui is the place to start. Pacific Digital Plaza Phase 2 is the place to start, conveniently connected to exit number 10 of the Metro station. There are more electronics markets nearby, such as Pacific Digital Plaza Phase 1 and Buynow. Popular game consoles are abundantly available as are computers, MP3 players, memory cards, and computer accessories. The Metro station exits at the intersection of five roads. There is at least one shopping mall on each of the five corners. Grand Gateway is the most upscale of them, and also the best-air conditioned in the summertime. The 5th and 6th floors of Grand Gateway offer a good selection of restaurants.
Ruijin Second Road is a tree-lined boulevard in the heart of the French Concession, where you can experience the real Shanghai longtang a narrow alley from house to house, which is a distinctive Shanghai architecture style. Don't forget to walk down Taikang Lu into Tian Zi Fang and burrow your way into the in process gentrification of the back alleys here. Old men air their magpies in spotless, tiny cages next to top flight restaurants and cafes. Shanghai T is a great place to buy a high quality T-shirt with a smart logo, "What recession?" Tian Zi Fang's renovation is still evolving and interesting shops and restaurants are opening and closing every day. The trendy stores exist side by side with the rhythms of "old school" Shanghai life -- and any time you can catch a glimpse of that, you should feel lucky.
Xintiandi (http://www.xintiandi.com/...) has both a mall and several small stores woven through the maze of reconditioned shikumen. Xintiandi is within the French Concession, but considered a sanitized, touristy and upscale "Disneyland" version of the original old neighborhoods it displaced. "Xintiandi" is supposed to expand and similarly transform a huge swatch of the French Concession later this decade.
