Where the closer way the get halal food from Inner Mongolia grand hotel beijing?

The nearest one is Muslim Restaurant at No. 104, Suzhou Hutong, Dongcheng District. It is about 200 yards to the east of the hotel. ;)

The Oriental Plaza is about 800 yards from the hotel. Walk north for about 350 yards, and turn left. Walk west for about 300 yards, and turn right. Walk north for about 150 yards to it. I am sorry that I have no idea of its opening hours. Yes, you can go to Lanzhou Beef Noodles Restaurant on B1, Oriental New World, Oriental Plaza, No.1 Chang'an Street. It is open from 09:30 to 21:00. Have a try!
