Samadhi Vegetarian Teahouse is located at the second floor of a buildin, which is very close to the SOS international clinic of Beijing (close to Liangma river). Restaurant is beautiful and peaceful. Food is not the cheapest in Beijing, but it's very good. Sometimes all the dishes and drinks listed on the menu are not available, but the menu is extensive.
You can also order their food via K.K.Rabbit Food delivery service: http://www.kkrabbit.com.cn/
