restaurant near Starway Premier Tianan Rega Hotel Beijing

Hi everyone. Is it easy to find a place to eat near Starway Premier Tianan Rega Hotel (within walking distance)?

1. We also think to visit Wangfujing Food Street. Is it possible to walk from our hotel? Can anyone provide direction?
2. I heard about Ba Guo Bu Yi Restaurant (Scizhuan Food) and Noodle Loft. How far are they from the hotel? What is the best method to reach the restaurants?

Is there any recommended restaurant that we should try in Wangfujing or Tiananmen area?

Thanks a lot.
