In my opinion, Shanghai is not a typical tourist place for foreigner traverllers, it's a commercial center in China, before time Xiangyang Market was attractive, but it's gone now. Xitiandi is also famous but it's not that special to most westerners. But the foods and restaurants in Shanghai are worthy to mention, you can find any flavor or style food you want here, as a cosmopolitan city, you can taste any food you want if you got enough money. If you want to locate the restaurant with specific flavor you want, just go to google typing "Shanghai restaurant" or "Shanghai food" to seach, then there will be a list of links for your choosing.
