Approximately less than one hour (Korea time) before the "HIGH HIGH" MV party starts, location of the party seems to be unknown yet. However, on Nov. 19th, there was a tweet by club_ROCOCO that said "지드래곤,탑,양현석씨와 함께 파티를 합니다. " which roughly means "G-Dragon, T.O.P and Yang Hyun-suk party together."
Club ROCOCO is a Boutique Social Club which is divided into SUPER ROCO - a Top Singer's Mini Concert, SPIN ROCO - a Celebrity Party with Celebrity DJ, etc. This club is located at B1, IP Boutique Hotel, 732-32, Hannam-dong, Yongsan-gu, Seoul, Korea.
So, could the "HIGH HIGH" MV party be held in this club ROCOCO? Based on previous tweet from Eugene Blake who is a Celebrity DJ, there is a possibility that the party will be held at the SPIN ROCO.
Ok, here is another tweet from a Adrienne Lee on Nov. 19th which says "In order to meet GD and TOP, visit to Rococo tomorrow!"
The party is on and now we know it's on Rococo club. Some images:
