As my colleague, H. (Chinese origins), explained for Chinese food is heaven so we decided today to enjoy a classic, namely Peking Duck. I have to words to explain the deliciousness, the tenderness and the flavor explosions which I experienced this evening. I didn't even manage to take a picture since I was so entangled in the process of savouring the duck. It an experience which I recommend you dearly if in China!
So in heaven, thus happy!
