Go to the Mc Donalds which is under the overhead train line [only 10m from the ticket gate].
Looking outside to the right you will see a wide street. You will see a TSUTAYA MUSIC shop on the other side of that street. Cross the street [there is a signal and pedestrian walk]. Walk to TSUTAYA and down the street beside TSUTAYA to the next street. Turn LEFT and walk to the next street. On the LEFT you will see HARMONY BAR. C'mon up the steep steps to the bar.
