Definitely Puxi is an adventure itself, majority of the people I know live in Puxi and transit to Pudong each day. I think Pudong overall was a success, I personally like how they built it up. Nanjing is fun near the Bund if I have the right area but don't forget about Maoming Lu. That's a totally different world compared to Pudong.
Thinking about it, it was porbably the fact that the trade shows were going on and brought in some roving groups to the Pudong Side.
