(on Shibuya map)
At the Hachiko exit of Shibuya station, you'll see big Hachiko crossing (with the big Tsutaya and Starbucks). Take the left street towards 109. 109 is in the centre of a Y-intersection, take the right street (Bunkamura-dori) and walk until you get to Bunkamura. Follow the street as it goes to the left of Bunkamura and take the 2nd street on the left (with Shibuya City Hotel on the corner). Go up the hill and pass Club Asia on your right, O-East on your left, and then you'll see an AM/PM convenience store on your right. Take the elevator next to the AM/PM up to the 7th floor.
