Kafa Bunna is a coffee shop on the second floor of a building across from Izumo Taisha Tokyo Branch, a 2-3 minute walk from Roppongi Station. It serves dark-roast coffee such as a Latin blend, brewed by nel drip. Founded in 1972, the shop has run for over 50 years and is now operated by its master alone, who is in his late 80s or older. When orders pile up, coffee can take more than 30 minutes to arrive.
