Feng Shui By Fishgirl can’t stress the need for yin & yang enough. You need yin (feminine ch’i energy represented by curves and rounded shapes and soft materials) to be in balance with yang (masculine ch’i represented by angles, squares, and hard materials) in order to achieve successful harmony, the essence of good feng shui. Recently I discovered the Miss Design blog where I found a post about a fabulous Tokyo restaurant. 
The architect used green sustainable design as well as good yin & yang details. Notice how these photos capture the mood of the place. Do you feel comfortable and at peace here? If you do, the architect and designer have done their job. Because a relaxed customer is someone who will spend more money at the restaurant. See more pics here.
