I will stay at Super 8, Longcheng, Huilongguan Longcheng Garden, Beijing, Changping.

Well, you can go to Adahi Halal Restaurant. The distance is about 450 yards (410 meters) to your hotel. As I know, the halal dishes are nice. And the prices are reasonable. It's located at the South Gate of North China Electric Power University, No.2, Beinong Road, Changping District.

Thank you...may i know only 1 muslim food therein beijing? most people can speak english or not since this is my first time go and i cannot read or speak chinese.

Of course not. There are many muslim restuarants throughout the city. You can easily find one. Don't worry! Most people can speak some simple English, and they will be very friendly to you. In addition, there are clear English guiding signs in the airprot, railway stations, metro stations, and scenic spots for your convenience. Have a nice trip!
