Niwo Teahouse, also known as "For Me For You", is known for two things: its exceptional service and its bird's nest soup and the tea, of course. The owner Ni Xiaoying is a graduate of Zhejiang University's Tea Studies program, and has studied the art of tea for over 20 years. She's also responsible for the shop's elegant interior design. Order one cup of tea and the rest is free, including fruit, snacks, and six varieties of dim sum. There's no minimum charge for renting out a room; just book ahead.
