I will be heading to Lanzhou for 5 days in early December. Has anyone been there recently? If so, do you have any recommendations on restaurants or things to do? I spent three months in Gansu in 2000, so I have already done several of the interesting excursions around Lanzhou (such as Xiahe, Lingxia, Bingling Si, etc.), but I don't know the city itself very well.

Thanks in advance.
