The miscellaneous and unpleasant atmosphere calms down. Unlike a club, it is not loud, so it is easy to talk with people. It's almost here at the second party after a large-scale drinking party with a certain number of people because it's large. I feel like a 2-chome HUB. At midnight on weekends, there were many groups dancing to idol songs of AKB and K-POP. The charge is cheap and the shots are cheap, so you can easily go. If you have a large number of people, it's easy to have a bottle ready at your seat with Kagamitsuki's bottle.
