On my first night in Shanghai, I headed to the Bund, which is the row of hundred-year-old buildings on the west side of the Huangpu River in Puxi, opposite Pudong. I took pictures on both sides of the river (there's a subway stop on the #2 line on each side). The buildings are lit up at night, which makes for a rather gorgeous sight.
