We have lived in Shanghai for three years now and this remains our favorite place in Shanghai. As the other reviewers document, the park is a popular gathering ground for Shanghai residents, including lone saxophone players, ballroom dancers, kids rollerblading. all manner of martial arts practitioners, kite flying and large crowds watching epic card and chess games. Shanghai does not have "open beverage" laws, so pack a bottle of wine or a couple of Tsing Tao tall boys, some snacks and spend a pleasant afternoon at the park. After, head across the street to Sinan Mansions for a beer at Boxing Cat.
