first, the stage and the sound system are quite nice, there enough toilets and prayer area. the down vote is, to think that promotor don't allow us to bring any drinks we buy from sponsors even snacks that promotor itself gave to fans are really weird. i've been attended so many kpop concerts but this is the first someting like this happened. you should tell us before the securities took it all. even worse, you told fans at CAT2 area to move to CAT1 while the singers are performing and don't let fans used stairs, only used 1 elevator that so dangerous because everyone try not to missed the performance but can't even move down. you should told fans to move seat when fans ready to enter venue after break. maybe it's because the first time you held kpop concert, so please improve for the next events. overall i still can enjoy all performances. thank you
