Classic cruise club in Busan. There are showers, rest rooms, and many private rooms in the spacious two-floor store. It is open 24 hours a day and you can stay overnight. The customer base is all genres, but the main crowd is over 30.
Go straight from Exit 2 of Beomil Station on Subway Line 1. Turn left at the corner of Busan Bank building. If you walk for about 1 minute, you will see a convenience store "CU" on your right, so it's on the 3rd floor of that building.
