I say "we" because I'm guessing you would enjoy these things as much as I would - or will - when I finally get around to my list.
Café del Volcán - I've been meaning to get over to visit the fine brewers on Yongkang Road for a while so I can add them to my Shanghai Coffee Guide. They bring in quality beans from all over the world but I'm hankering to learn more about Yunnan coffee and taste it. I brought back a bag from Dali when I was there last September and really enjoyed it. And I'm paying way too much for imported Italian beans from the supermarket. I need to go local.
China Art Museum - Shanghai's China Pavilion has been turned into the China Art Museum that opened at the beginning of October. In addition to its large collection of traditional Chinese art, it is currently exhibiting a collection of 19th century paintings from France's Musée d'Orsay. The show "Millet, Courbet and French Naturalism" will run until February, 2013.
Shanghai Biennale - this art event is on for the 9th time and being showcased this year at another former Shanghai Expo venue re-dubbed Power Art Station. The venue is huge and rumor has it that you need to book tickets in advance, but everyone I know has just shown up and gone in. I'll go find out and report back.
I'm sure there's even more out there that I'm missing but those are three pressing things I'm going to try to tick off my list before the month is over.
