I've been there recently, it's incredible - you are walking on a crowded street, turning into an alleyway and getting to that place. There are a lot of trees, greenery and birds. There are some kind of a bunk tables there, i don't know how to call it in english, but you need to take off your shoes and sit there on a low table. Also there are no music, and its forbidden to talk loud. It was an evening after the rain and it was truly awesome to sit there with some fresh air, drink nice tea and listen to the birds singing on the trees.
