This gigantic waterside club is Tokyo's largest, complete with a pool and food trucks. Best to come in a group and definitely check the schedule in advance (there's not always something happening and events vary). Free buses run between the club and a bus stop on the east side of Shibuya Station (on Roppongi-dōri) all night. Cover around ¥3000; bring photo ID.
