Hi, you could take the airport shuttle bus night line and get off at People's Square. From People's Square metro station, take exit 1 and walk along Xizang road keeping the park on your right hand side. Cross over Wusheng road and continue straight ahead. After a minute, you will see a pedestrian overpass in front of you. Go up the stairs and bear left. Cross over Xizang road and take the stairs down to the right. Yunnan road is the first right hand turning. There's a beautiful restaurant styled like a Mosque to help show you the way! You totally need to walk about 10 minutes.
