If you find yourself in Sangenjaya I highly recommend to set some time aside for coffee and cake at this café. Interior speaks for itself and overall atmosphere is very soothing with soul and jazz playing in the background. It is a little bit on the expensive side for a cup in Tokyo (700yen for a hand drip) but coffee (and chocolate cake) is truly great and you could easily spend a few hours reading a book here. Good to know is that the cafe has a sister in Kyoto, Elephant factory coffee, just as great as this one.
