I didn't put it in the map, but it is the same building as Blues Bar only on the 3'rd floor, a few doors down from Hunter's Bar. Also not shown on the map there are alleyways across from Jungang Station that you can pretty much walk directly to the building. Just go through the alley next to Lotteria. Go past the first street and when you come out you will be kind of close. Also a note, the number of buildings on the map is not an exact replica.
