1. at Shanghai Maritime Univeristy, you could take the metro subway Line 6 at Minsheng Road station and then transfer to Line 2 at Century Avenue station. Finally, please get off at Jiangsu Road station and go out from Exit 4 or 3 to Jiangsu Road, along which you could walk to the Huamin Empire Plaza in 10 minutes.
2. it is suggested that you take a taxi from the university to the Oriental Hospital (东方医院), where you could catch the shuttle bus Line 5 to Pudong Airport.
Alternatively, you could take the metro Line 6 and then transfer to Line 2 to get ot Longyang Road station. Here, you could take the Maglev train to Pudong Airport in 10 minutes.
3. the distance from the University to the restaurant is only about 1.5kms, so I think you could hire a cab to arrive there directly.
