World class Live band on one side DJ in the other. One of the "in" places in Seoul for a night on the town. Strictly high end here- dress up and bring your $$$s.

Located iin Grand Hyatt basement is a good place with two different atmospheres. On right side the disco club, with a nice bar, a dancefloor and a beautiful terrace for summer time and on the left a live music spot. Nice atmosphere, trendy people and good service, at a price

$15-20 for a drink. That sobered me up in a hurry. Great set up but those prices do not match the area and limits the crowd. I have money but this isn't Vegas baby...

I was staying at the Grand Hyatt with work, our Seoul counterparts took us to JJ's for a party - the layout is brilliant and quality of booze is fantastic. A great setting to chill with friends or party hard with great music and dance floors.

I love this place with its elegant and spacious bars. Good location at one of the best hotel in town. Very close to Iteawon where you can meet some Korean who speak good English. I highly recommend this bar. Cheers,

My friends and I visited this nightclub a few times during our 6 day stay in Korea....The bartenders and band were excellent. This was the most trendy club with the most beautiful people I saw in one place during my stay....Highly recommend it...Great times....

Looked ok but essentially deserted when I was there (around 9pm on a Thursday night). Probably better on weekends- had two large security guards outside the entrance despite no crowd.

Many Hyatt hotels have fun bars, this one too, with a mixed crowd. Band is great and entertaining, also the DJ area is very good. Great atmosphere. I didn't try any food, the drinks were ok, very pricey though for what you get. A good place to go after drinks in Itaewon.

We love the Hyatt, but JJ Mahoney's that is attached doesn't have the best food. My partner (vegetarian) really loved one of their pizzas, but they have since changed their menu and no longer offer the pizza so now we no longer have a reason to eat there. Can't say much about the nightclub/lounge as we have never stayed around... More 

Thank Meagan L

Staying in Itaewon

Neighbourhood Profile
Neighboring the immense Yongsan American Garrison, Itaewon was once shunned by locals as a seedy, red light district. But within the past few years, Itaewon and its surrounding neighborhoods such as Kyunglidan and Haebangchong have undergone a major revival to quickly become one of Seoul’s hottest areas. Here, trendy international restaurants dot the area alongside hip lounge bars and some of Seoul’s hottest club venues. After dark, Itaewon comes into its own as one of Seoul’s top party scenes. The crowd is a fascinating patchwork of all backgrounds and identities, including a small but thriving Muslim community (centered on Korea’s sole mosque), the LGBT community (with a string of popular bars and clubs), and a wide range of ethnicities and cultures scattered around. Those seeking a quiet respite should head towards the eastern end, in Hannam-dong, which not only has one of Korea’s best art museums, the Leeum Samsung Museum of Art, but plenty of mid-range to upscale restaurants and cafes.
