All I know is that there is one on Nanjing East Road. Take subway 1 Line or Line 2 and get off at People's Square, then walk through Nanjing Road Pedestrian Street. There is another one in Tianyaoqiao Road, which is Xujiahui. Get off at Xujiahui on Metro 1 Line and walk along Tianyaoqiao Road. You can see a monopoly on the pedestrian street.
