p.s. A great budget hotel ($35 USD last time I checked) in Shanghai is the Xin Kaifu Hotel. It's about 10 mins. walk from the Bund. Very nice place, very nice people, their english is a little rough. If you eat in the hotel restaurant make sure you have the lemon chicken (if they still have it).

Here's the link:
