WHERE TO EAT
Visiting a teahouse is a must in Hangzhou but which one? I recommend the Hupanju Tea House on West Lake (23 Hubing Road, No. 1 Sheng Tang Scenic Area, Xihu District,  8702-0701). Along with outstanding views, Hupanju offers every sort of luxury tea imaginable, including the famed longjing tea. Price varies but I spent less than $20 for tea, food and two hours of loitering.
Kuiyuan Restaurant, 154 Jiefang Road, serves outstanding noodle dishes. Eel is the house specialty at this century-old restaurant. Dinner cost about $3.
