Matthias, can you be more specific what's wrong or how you want it to be changed. The website says:
JR Pub: From Seoul Pub, walk around Gecko's into the small alley leading downwards, it's on the right hand side (groundfloor) just before Wolfhound.
Bulldog: Above Gecko's on 3/F, at the main intersection in Itaewon, opposite Hamilton Hotel.
While it might be the same building, entrances to the bar are at different locations. I have been in both venues, and I believe the description is good enough to find it. Or are you referring to the map? The dot might have been a little too far down the alley, but everybody who walkes through that alley will find JR Pub easily. I have moved the dot up a little bit (don't forget to refresh the page).
