Beijing - there for a month - what to do?

[Ynox]

Hi,

Getting sent out to Beijing for a month (this weekend if my visa is sorted in time!).

Going to be working 5 days a week but should hopefully have weekends free to do stuff. Anyone got any suggestions of absolute must sees / stuff to avoid?

Also - going to be staying in http://beijing-east.frasershospitality.com/ (East CBD as it's close by my office). Any suggestions of good bars / restaurants nearby will be well appreciated.

Thanks,

Mike
