$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 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,
