Ping Pong and beer
Table tennis is quite often played at leisure while drinking, much like billiards and darts. EST Shibuya Takkyuu Club is located close to Shibuya station on the 9th floor of an entertainment center. Open until 4:30AM (Mon-Thu) and 5:30AM (Fri-Sun) it makes for a fun hide-out if you have missed the last train and are not up for a club or manga cafe.
